LMP7721: LMP7721 / LMP7715 Based AFE for pH and ORP Sensors: Guard Ring, Supply Architecture, and BNC Guard Signal Questions

Gustavo Adono — Thu, 14 May 2026 18:34:11 GMT

Part Number: LMP7721
Other Parts Discussed in Thread: LMP7715

Hi everyone,

I am developing a dual-channel analog front-end (AFE) for pH and ORP electrochemical sensors using components from Texas Instruments. The expected output signal ranges are ±414 mV for the pH electrode and ±1500 mV for the ORP electrode. My design is based on the LMP7721MAEVALMF_NOPB evaluation module as a reference, and the active components selected are the LMP7721MA/NOPB (femtoampere-input-bias-current op-amp for the high-impedance pH front-end) and the LMP7715MFX/NOPB. I am attaching the schematic and PCB layout for review and have the following questions:

**1. Guard Ring: Extent and Solder Mask Clearance**

In the reference EVM, a guard ring driven at the same potential as the non-inverting input of the LMP7721 is used to reduce leakage currents on the PCB surface. I would like to clarify:

What is the recommended extent of the guard ring? Should it surround only the op-amp input pins and feedback network, or should it also enclose the full signal path up to the sensor connector?

Which copper areas and traces must have solder mask removed (i.e., exposed copper) to minimize surface leakage currents, and which areas should retain solder mask coverage? Is it sufficient to open the mask only around the high-impedance nodes, or should the guard trace itself also be mask-free?

Is ENIG (Electroless Nickel Immersion Gold) the recommended surface finish for the exposed copper areas, and if so, what makes it preferable over other finishes such as HASL or OSP in this context, particularly regarding surface leakage and long-term oxidation on unmasked high-impedance nodes?

**2. Power Supply Architecture and Signal Chain Compatibility**

The LMP7721MAEVALMF_NOPB EVM uses a split (bipolar) supply (V+ and V) for the op-amps. In my design, the output of the AFE feeds a differential-input ADC rather than a single-ended ADC.

Is a differential ADC topology appropriate for this application, given that the sensor signals are inherently single-ended with respect to a reference electrode? Or is a single-ended-to-differential conversion stage recommended before the ADC?

Considering the signal ranges of ±414 mV (pH) and ±1500 mV (ORP), do the dynamic ranges of the LMP7721 and LMP7715 output stages, as well as the ADC input range, adequately cover these levels without clipping, particularly if a single-supply or low-voltage split supply is used?

What split-supply voltage would you recommend (e.g., ±2.5 V, ±3.3 V) to maintain linear operation across both signal ranges while keeping the common-mode input and output within the specified headroom of the LMP7721?

**3. BNC Connector: Guard Signal on Pin 2**

I understand that triaxial connectors are the industry-standard choice for high-impedance electrochemical measurements, as the driven shield (inner coax) provides guarding directly at the cable level. However, due to project-specific mechanical and cost constraints, I am required to use standard BNC connectors.

In a BNC-based implementation, is it correct to connect the driven guard signal (i.e., the bootstrapped output of the unity-gain buffer driven at the same potential as the electrode signal) to Pin 2 (the outer shield/shell) of the BNC connector?

Any feedback on the schematic and layout, especially regarding PCB leakage mitigation, supply decoupling, and signal integrity at these impedance levels, would be greatly appreciated.

Thank you.

THS4551: THS4551 VOUT+ Saturating to VS+ Regardless of Input

Thejas B M — Thu, 14 May 2026 13:09:34 GMT

Part Number: THS4551
Other Parts Discussed in Thread: ADS7057,

Dear TI Team,

We are using the THS4551IRUNR as a differential driver for the ADS7057IRUGR ADC based on the reference design approach suggested in the ADS7057 datasheet. The schematic will be attached for reference.

Issue observed:
The FDA output VOUT+ is saturating close to the positive supply rail (VS+ ≈ 4.3V) regardless of the applied input signal condition, while VOUT− remains around ~1.7V.

Observations:
• VOUT+ saturates close to VS+ even when the ADC input is isolated
• Behavior remains similar across different input conditions
• VCM is generated using AVDD/2
• THS4551 is powered from a single 4.3V supply
• ADS7057 AVDD is 2.8V

We would like your guidance on:
• Possible reasons for asymmetric output saturation in this configuration
• Any stability or compensation considerations for THS4551 while driving ADS7057
• Whether this could be related to common-mode operating range or feedback network implementation

Kindly review the attached schematic and provide your suggestions.

Best regards,
Thejas B M

TAS5828MEVM: Using two TAS5828MEVM boards with PPC3

Sebastian Brett — Thu, 14 May 2026 11:55:13 GMT

Part Number: TAS5828MEVM

Hello,

I'm trying to use two TAS5828MEVM boards together to build a 4-channel active stereo setup (left/right tweeters and left/right woofers).

My aim is to connect both boards to the same I2C bus, with Board A acting as the controller and Board B as the target, so I can control both from a single instance of PurePath Console 3, with each board having its own I2C address.

So far, I have:

Moved the J14 bridge to J18 and J15 to J16 in order to configure both amplifiers to be powered with an external 20 V DC PSU.
Connected Board A to my PC via the micro-USB interface; this board is detected by PPC3 and works normally.
Powered Board B from a separate 5 V USB charger and connected SDA, SCL, and GND between the two boards (via the TP20, TP19, and TP11 pins on each board).
Set Board B to HW address mode by moving J8 to the HW position.
Added a 1 kOhm resistor from the ADR pin (centre pin of J8) to GND on Board B, which I understand should set the register address to 0xC2.

Board B powers up correctly, but when I try to select the custom configuration in PPC3, I get a message saying that it cannot be detected.

I also tried connecting both boards directly to the laptop via USB, but PPC3 then failed to detect either board.

Could you please confirm:

Whether it is possible to use two TAS5828MEVM boards in this way with PPC3.
Whether my address configuration for the second board is correct.
Whether any other jumper settings need to be changed.
How I can verify that the second board is responding on the I2C bus.

My end goal is to use two TAS5828MEVM boards as a 4-channel DSP amplifier platform for an active stereo speaker system.

Thanks very much for your help.

Best regards,
Sebastian

TLV2361: Is the intention to evaluate TLV2361 with hardware samples since no PSpice model is available?

Hori Shota — Thu, 14 May 2026 01:27:32 GMT

Part Number: TLV2361
Other Parts Discussed in Thread: TLV9061, TLV6741

Hi team,

Regarding this E2E discussion, I would like to confirm my understanding.

Is the intention that, since TLV2361 cannot be simulated in PSpice due to the lack of a model, we should request device samples from the sales team and perform an evaluation using actual hardware instead?

Please let me know if this interpretation is correct, or if there is an alternative recommended approach.

Best Regards,

Other Parts Discussed in Thread: OPA862, OPA837, OPA836, THS4531, TLV3211

Hi,

I am designing the difrential amplifier using opamp upto 2.5MHz. But opamp due to multiple stage quiescent current is increses. I need to achieve less than 1mA current. So is that possible we can use instrument opamp IC. Please suggest. Design requirement is mentioned below:-

1) difrential signal is coming 300mVpp and due to this signal we need to amplify with hysterisys and generate clean PWM which is sync with input if input have 2.5MHz then output of pwm is also 2.5Mhz.

I was previously able to get the ADS1235EVM working correctly with the Arduino UNO R4 WiFi, and I included the working setup configuration above for reference. However, I have not been able to get it working properly with my RA4M1 evaluation board using e² studio.

Any advice or suggestions on what I should check next would be greatly appreciated.

AMC23C12: Clarification on threshold/reference voltage setup, and input protection.

ArTzy — Tue, 12 May 2026 19:11:28 GMT

Part Number: AMC23C12

Hi Experts,

I am currently designing a circuit using the AMC23C12 and would appreciate some clarification on its threshold voltage calculations, reference voltage setup, and input protection.

With a nominal input voltage of 0.385V and an operating current of approximately 4mA, I want to confirm if the threshold voltage is set 250mV above and below this 0.385V level. Based on this, would the high and low trip thresholds to shut the output off be 0.635V and 0.135V, respectively?

Consequently, I am assuming my reference voltage should be set to 0.385V, which leads to a reference resistor calculation of (0.385V - 0.004V) / 100uA = 3.81k ohms. Please let me know if this math and logic are correct for this device.

Finally, I would also like to know if the AMC23C12 features internal input protection to prevent damage from high-voltage transients or spikes.

Thank you.

Regards,
Archie A.

AMC1350: Inquiry on Voltage Sampling with AMC1350DWVR

alps zhang — Tue, 12 May 2026 12:35:31 GMT

Part Number: AMC1350
Other Parts Discussed in Thread: AMC3330,

Hello,

I am using the AMC1350DWVR to sample the input voltage (220V/50Hz) and output voltage (400V) of a totem-pole PFC converter.

The 5VP is generated by the auxiliary power supply and shares the same ground as the DC bus voltage, which is the power ground PGND_P.

P5V is the 5V analog power supply, and AGND_P is the analog ground.

The signal goes through AMC1350DWVR for isolation first, then an op-amp for sampling and conditioning.

I would like to ask: Is the ground reference for my voltage sampling correct? I have always been confused about ground partitioning. Is my voltage sampling circuit design correct? If not, how should I modify it?

Also, are there any integrated chips that combine isolation and op-amp sampling functions in one device? Could you recommend some reference parts?

Best regardsSCH_Schematic1_5-P1_2026-05-12.pdf

Does the TAS2783 exist. I am looking fo the smart audio amp for soundwire for an Intel Panther Lake design. I see mentions of it.
