ADS131M04: Maximum Simultanious Sampling Rate for all channels enabled

Shubham keshari

Part Number: ADS131M04

Tool/software:

As i connected this ADC and I am not able to fetch more than 4 Ksps on 1 channel.

After setting these parameters (OSR - 128) (using ADC in HR mode) what will be the maximum simultaneous sampling rate which can be achived through this ADC ?

    Hi Shubham keshari,

    If the clock of your ADS131M04 is 8.192MHz and the OSR you set is 128, you should be able to get 32ksps data rate, this is the data rate per channel of your ADC because ADS131M04 is a simultaneous sampling ADC. 

    If you still get 4ksps data rate, your register writing probably was not successful because 4ksps (1024 OSR) is the default data rate in HR mode. Please read the CLOCK register back to check whether your OSR setting was successful or not.

    BR,
