Part Number: ADS131A04 Other Parts Discussed in Thread: AMC1350 , THP210 Tool/software: For this circuit, we have a signal that is +/-7.5VDC input and want to read it on the ADC. We send the input signal through the AMC1350DWVR (U39) to isolate the signal…
Part Number: ADS131A04 Tool/software: The datasheet indicates the RESV pin hard tied to IOVDD.
Customer would like to tie IOVDD through 100 Ohm to better check soldering, etc...
Is this OK? What is the max value of resistor that could be used? (Obviously…
Part Number: ADS131A04 Other Parts Discussed in Thread: TLV171 Tool/software: Hello, everyone,
I'm working with the ADC converter ADS131A04 in unipolar analog power supply mode (3.3V) with negative charge pump enabled. The purpose of the work is to measure…
Part Number: ADS131A04EVM Tool/software: We are working on ADS131A04EVM Board. We could communicate with the device and the commands and response working as expected.
The problem we are facing is the DRDY pin shows always LOW. What we understand that…
Part Number: ADS131A04 Tool/software: Hi, may I know what step am I missing? I have been trying to get the ready response from the chip (FF04) but so far only successfully getting FF82 even though I have sent the NULL command two times in a row.
Part Number: ADS131A04 Tool/software: Hi, I am using the ADS131A04, 16-bit with 4 channel asynchronous interrupt mode,
ADC configurations are:
0x0B A_SYS_CFG 0x78 (VCP off, High res EN, VREF4V, INTVREF)
0x0C D_SYS_CFG 0x3C
0x0D CLK1 0x02 (CLK_DIV…
Part Number: ADS131A04 Dear expert.
Do we have the DSP code for the ADS131A04? Customer want to refer the design as below but the setting occur the problem

Part Number: ADS131A04 I am considering using the ADC evaluation board (ADS131A04EVM) to measure a 5kHz input signal with a sampling rate of 80kSPS or higher (for example, with a setting of 128kSPS).
I would like to measure the sampling jitter to be…
Hi Taile,
Your question: " From the above table, does this mean the max and min voltage being applied to either AINP or AINN should not exceed this range [AVSS - 0.3 to AVDD +0.3] if charge pump is disabled? "
Answer: Correct. If the voltage applied…
Hi priti gaikwad,
Your schematic is still too blurred to see even I zoomed it in, you can open the image you uploaded to check.
It seems like you have connected REFN pin to +Vref through a resistor (R13?) as shown below, not AVSS:
You can re-upload your…
