I would like to check which TSW EVMs would work as alternatives (on the ADC12J4000EVM website it only suggests TSW14j56EVM as the corresponding evaluation board). I require a 4GHz sample rate without decimation (so in BYPASS mode). My understanding is that the TSW14J50EVM does not have a sufficient lane rate for this (6.5Gbps which is max sampling rate no decimation of 3.25GHz) . I have a few questions: Is my understanding of the sampling rate of the TSW14J50EVM correct and is it compatible with the ADC? Are the TSW14j57 and 58 EVMs both suitable alternatives and compatible with the ADC? Would you also be able to offer other suitable boards that meet this sampling rate requirement? (Or if not within close range) Would TI ever restock the TSW14J56EVM or have any stock currently?

How good is the matching of the ROFS|RFB resistors and woutd it make sense to include this value in the electrical characteristics section of the datasheet (or did I just miss it)? Looking at Fig. 6-31 and 6-32 the glitch occures roughly 1.4us after the falling edge of LDAC. I wonder why this is so late. What setting of UP_RATE was used for these figures and I would be very interested to see what UP_RATE=01 look like?

According to our calculations, 50 kOhms is enough to comply with the maximum current in Default condition (50 uA theshold) but not with the one for Normal Condition (10uA). Is there a recommendation on how to reach and document compliance in NC ? Can we consider the AFE itself as a MOPP during the certification process ?

We&#39;re using an ADS1299 development board purchased online. This board integrates the ADS1299 configuration file into the MCU chip, and it can detect valid signals on the human body. We suspect the problem lies in our ADS1299EEGFE-PDK configuration error. Could you provide a verified configuration file so we can import it and try it?https://e2e.ti.com/support/data-converters-group/data-converters/f/data-converters-forum/1658066/afe882h1-sleep-mode-current/6394397Thu, 25 Jun 2026 00:12:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:c0819db9-8c94-4c96-b457-5d38398a5714Lucas BurnetteHi Anurag, Let me check this out and I will get back to you shortly.

I believe I saw similar behavior to what you were describing using the SYNC command, but let me review further and run some more tests before I make any definitive statements I did also try the SLEEP + WAKEUP commands, which seemed to give me much better results. Have you been able to try this method? I would issue the SLEEP command then the WAKEUP command, holding CS low during this time (see the note on page 45 in the datasheet). Then I would wait for DRDY to drop low, then clock out data using the RDATA command. Then repeat this process. The time between the first SLEEP command and the subsequent SLEEP command is your sampling rate i.e. 600 SPS, whereas the ADC data rate can be different -Bryanhttps://e2e.ti.com/support/data-converters-group/data-converters/f/data-converters-forum/1657381/ads125h18-connecting-resp-to-refout-for-single-supply-operation-with-bipolar-inputs/6394200Wed, 24 Jun 2026 20:05:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:94b3052c-15ae-40e1-a6dd-ac2d324169e6Leo AhlinThis now makes sense.

That pin is the RESN pin, so all of the single-ended inputs are measured with respect to RESN, not AINCOM. And since you should ground the RESN pin then all single-ended measurements are taken with respect to ground, through the resistor divider of course. This will be fixed in a future revision of the datasheet -Bryanhttps://e2e.ti.com/support/data-converters-group/data-converters/f/data-converters-forum/1658045/ads1299eegfe-pdk-ads1299eegfe-pdk-software/6394137Wed, 24 Jun 2026 19:15:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:15c7e929-9195-48a2-85f7-8897d98ac77fRyan AndrewsHi Dapeng, The EVM for the ADS1299 is meant to be used with bench equipment or patient simulators, but not with the human body. Legally, we cannot recommend you test with live human subjects as our EVMs are not certified for patient safety. Can you try applying a known input signal from a function generator to ensure that you have a valid register configuration?

Q1: Correct. Q2: Yes. Q3: Yes. Q4: The following settings are needed for TC measurement: Select AIN6 and AIN7 as AINP and AINN. Select an appropriate Gain. Enable REFP_BUF_EN that will enable internal REFP reference buffer. Optional: select an appropriate OSR for your desired data rate. Capture data. The pullup resistor provides an option for burn-out detection without a separate measurement, it is not related to the register settings.

Daisy chain mode requires 4-wire SPI mode to be activated. In 4-wire mode, &quot;if the access cycle contains multiples of 24 clock edges, only the last 24 bits are used by the device first device in the chain.&quot; Fresh chips off the shelf boot into 3-wire SPI mode by default. In this mode, &quot;only the first 24 bits are used by the device.&quot; Therefore, it seems that it is not possible to enable 4-wire SPI for chips wired in a daisy chain unless they are initially not connected in a daisy chain or have their NVM pre-programmed to default to 4-wire mode. This conclusion seems to be corroborated by this forum post regarding a similar part, in which a TI employee states, &quot;For daisy chain mode, there is a caveat that you must be able to short all of the SDI lines together to send a command to enable the SDO pin and save this in the NVM. Otherwise, the second DAC in the chain will try to capture the first 24 bits in the frame instead of the last 24 bits.&quot; Is my understanding correct? Is there any way to enable 4-wire SPI/daisy chaining for chips that are wired in a fixed daisy chain? If not, does TI support NVM pre-programming or recommend 3rd-party vendors that have pre-programming and re-reeling capabilities? This issue is of high urgency, so your prompt response would be greatly appreciated.DAC63004https://e2e.ti.com/support/data-converters-group/data-converters/f/data-converters-forum/1657893/ads8684-able-to-survive-a-single-ended-negative-voltage/6393746Wed, 24 Jun 2026 14:44:00 GMTcb01d8b2-d089-468d-babb-77d1d8683490:a02b8f16-fd88-459c-8355-1cabe31b8118Cameron WutzkeThank you!!!

Voltage monitoring is the only channel which I would like to connect via a resistive divider to PSS_IN, the respective voltage to be monitored. PSS_U goes to the ADC via an analog switch. 130 mA is way more than necessary, but what exactly does &quot;momentary&quot; mean? In case of wrong cabling, PSS_IN may be at -32 V, so current flow through the protection diodes may be present for some time (until the technician becomes aware of his/her mistake), my guess is some minutes, maybe an hour. Just want to make sure that this wouldn&#39;t damage anything (e. g. if &quot;momentary&quot; means a duration in the ESD pulse timescale / some 10 ns).
