Part Number: ADS122C04 We are using Ain0 and Ain1 to measure a pseudo-differential ±2.0V signal. We have ±2.5V for AVDD and AVSS and are using AVDD and AVSS as references. The current termination of the signal before the ADC inputs is a configuration…
Part Number: ADS122C04 Because I wanted to measure 100uV signal, it was found in the test that the signal measured after opening PGA did not match the actual signal. The waveform I measured was a sinusoidal signal, and what I actually got was a noise…
Part Number: ADS122C04 1. Under the condition of single power supply, can the differential input mode be negative (i.e. Vp<Vn)? 2. If the internal reference voltage 2.048V is used, how should the REFP and REFN pins be connected? Should they refer to…
Part Number: ADS122C04 I am seeing a reading on one channel being affected by the voltage on another channel. Confirmed the actual voltages on the pins are as expected.
The problem can be solved by reading the channel twice and only using the second reading…
Part Number: ADS122C04 Hello,
I try to get my head around this but I cannot find an issue.
I see depending on the gain different amount of deviations:
Following is the wiring diagram. To the ADC a strain bridge simulator is connected, simulating the…
Hi Jyrki,
I'm glad to hear that it now working. Sometimes you need to take a step back or do something else for a while and then things start to work.
Best regards,

Part Number: ADS122C04 hi, Dear product line engineer.
my customer has inquire: whether or not is there any register for store chip ID and revision in ADS122C04? my understanding is no. Am I right? thanks.

Below is my circuit diagram,
The logic is very good at SPS 20.
But when I try to set SPS 45, the output value is not stable.
Below is my data.
1) SPS 20
2) SPS 45
Below is my process setting value. (processor : Atmega328P…
Part Number: ADS122C04 Hi,
we experience a strange behavior on a new design using ADS122C04.
Reading data using I²C is providing 2 bytes instead of expected 3.
Moreover, applying different current levels in ipnut provides expected output but in…
Part Number: ADS122C04 Is the process below correct for acquiring and calculating temperature from ADS122C04 connected to a K-type thermocouple? If not what mistakes are being made?
I am using this manual https://www.ti.com/lit/ds/symlink/ads122c04.p…
