When I increase the DAC voltage from 0 to 4V, the output of TLV and the output of XTR increase quite consistently according to the formula. However, until the DAC voltage reaches 20mV, I see 13mV at the TLV output and 50mV at the XTR output. So there's a constant offset at the TLV output. All resistors have a 0.1% tolerance. Any device operating on 0-10V (motor driver, fan speed controller, heater, etc.) can be connected to the socket. It doesn't matter if the output is 0V and the load at the output isn't driven when I set the OD pin to 0. I want to turn off the output when I set the OD pin to 0. This system has many communication, read/write, and analog IO's. I need to protect the system from noise. Thanks.https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1630175/lmh13000-can-lmh13000-en-ep-pins-be-driven-by-ds90lv011a/6298277Tue, 07 Apr 2026 10:45:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:916ae139-0c16-4ea2-9e86-2ea994bde11bAndi IlmyAnant, Thank you for your explanation. I have a follow-up questions regarding the biasing the EN pin. I tried simulating the EP-EN control while biasing the EN pin using the output of a 50% Voltage Divider from a 3.3 V input in TINA-TI. Performing transient analysis would result in the EN pin voltage to mirror the EP voltage. Is this just a model issue and won't be reflected on the actual component? Attached is the simulation file. e2e.ti.com/.../Laser_2D00_Diode_2D00_Driver_2D00_M2.TSChttps://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1633835/ths4536-can-this-device-be-used-for-attenuation-gain-1Tue, 07 Apr 2026 09:12:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:8b753c98-1300-4946-8e93-40513af352a6Hori ShotaPart Number: THS4536 Hi team, When using the THS4536 with a +5 V single supply, is it possible to directly apply a ±10 V input signal and attenuate it to 1/10 or 2/5? (The device will be used with Vocm = 2.5 V.) In other words, can the device be configured with a gain of G = 0.1 V/V?

Wie hoch dürfen die negativen Ströme sein? Wann geht das Bauteil in die "overload condition" und wie lange braucht der Baustein für die "Recovery"? Ich möchte den Baustein für eine Strommessung über einem Shunt Widerstand verwenden. Im Normalfall werden nur positive Ströme gemessen. Allerdings kann ggf. ein kleiner Rückstrom auftreten, den ich in meinem Design beachten muss. Hier ist der Ausschnitt des Datenblatts zu dem Thema: 7.2.2.1 Overload Recovery With Negative VSENSE The INA950-SEP is a unidirectional current-sense amplifier that is meant to operate with a positive differential input voltage (VSENSE). If negative VSENSE is applied, the device is placed in an overload condition and requires time to recover when VSENSE returns positive. The required overload recovery time increases with more negative VSENSE. Mit freundlichen Grüßen, Britta KuttruffINA950-SEPhttps://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1632468/lm6172qml-output-stage-explanation/6297978Tue, 07 Apr 2026 07:18:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:dc5b5930-7bb8-4d76-b111-991933fe0877Michail-Angelos ZogalisHi, in the past we passively tested two other LM6172QML in the same configuration and the resistive values were consistently in the several MOhm range(for both opamp channels). This is the first time that i see such a low value and its only on one of the two amps in the IC. The fact that the resistance between the output pin and the rails(pos, neg) remains dead set to this low value even after powering up is alarming to me(feels like an actual leakage path). The specific opamp in this package is an outlier but i cant completely justify my position here.https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1632267/ina125-ina125---offseting-the-input/6297979Tue, 07 Apr 2026 07:18:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:7d47ca49-c230-48d7-91a3-c9873a63048cGregor MacekDear Robert, thanks for your answer. In the midtime I already found I have an issue with reversed Vin+ and Vin- nodes - after reversing, all works fine. Anyway, I have another problem/issue: is there possible to offset input in order to have a bit room for negative direction on the load cell? I found Offset trimming (Fig 2) option in datasheet, but If I understand correctly, this will only affect output?

As a rule of thumb, if your signal trace length is less than 10times of wavelength of the highest frequency component of the signal, then in that case the signal reflection will be negligible and hence you can eliminate the impedance matching. In your case your trace length is around 0.1m so for signal have wavelength > 1m (10time of 0.1m), you need proper termination. Wavelength of 1meter corrosponds to ~300Mhz signal. So if your LVCMOS signal rise time is around < ~1.2ns (tr = 0.35/300MHz), you should consider impedance matching.

OPA inputs IN+ and IN− (Pin5 & Pin6) are intentionally shorted together (fault injection / stress test). This condition is understood to be outside normal operating conditions. Observed Behavior Two TLV9152‑Q1 samples show different behavior under the same test condition: Sample A With IN+ / IN− shorted: OPA output / MCU I/O remains logic LOW Behavior is as expected due to MCU pull‑down. Sample B With IN+ / IN− shorted: OPA output (PIN7) / MCU I/O is pulled up to ~3.3 V (logic HIGH) As a result, the MCU detects I/O as HIGH. Verification Performed To rule out MCU-related causes: The series resistor R26 was removed, disconnecting the OPA from MCU. Result: Both samples show identical MCU behavior. MCU I/O pin briefly goes HIGH (~20 ms) during MCU power‑up, then is pulled LOW by the internal 100 k pull‑down. This confirms: MCU reset / firmware / internal pull configuration is not the source of the difference. The difference only appears when TLV9152‑Q1 output is connected. Questions Why do these two samples exhibit different behaviors? Is this difference caused by sample‑to‑sample variation in the op‑amp output current when the inputs are shorted, resulting in one MCU IO being pulled above VIH (logic HIGH) while the other remains below VIH (logic LOW)?TLV9152TLV9152-Q148V in automotivehttps://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1629462/amc1311-q1-hv-monitoring-circuit-design-assistance/6297711Tue, 07 Apr 2026 03:38:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:cf49b649-fcc9-436f-a258-608e2d7b70b5Preerag MIs there any method to analyze the stability of AMC based circuits?https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1629606/am2754-q1-am2754-q1-opsi-flash-design-question/6297682Tue, 07 Apr 2026 03:03:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:87fbb501-4321-4616-99b5-a40d91e8205aAndreTsengAnastas, Any feedback, customer want to finalize their schematic design.

For more details, see the TI Space Products Guide . In the same vein, there are also differences between the engineering evaluation model of the LMP7704-SP and the fully qualified version: [quote userid="91605" url="https://e2e.ti.com/support/amplifiers-group/amplifiers/f/amplifiers-forum/1618306/lmp7704-sp-part-number-confusion"]TI engineering evaluation (/EM and -MPR) models are units intended for engineering evaluation only. While using the same die as fully qualified and processed space-grade products (QMLV or products appended with the suffix -MLS), they are processed to a noncompliant flow (for example, no burn-in) and tested to a temperature rating of +25°C only. These units are not suitable for qualification, production, radiation testing or flight use. Engineering models are not specified for performance over the full military specified temperature range of –55°C to +125°C or for operating life.
