ADS125H02: how to properly switch MUX between AIN0 and AIN1

Part Number: ADS125H02

Hi,

in my application I need to switch the input MUX repeatedly between single ended inputs AIN0-COM and AIN1-COM.

1) Is there any time constraint on how fast that can be done?

2) is there a proper workflow to go through before and after the switch (e.g stopping conversion, delaying the restart, etc) ?

Thanks for your support

  • Hi Marco,

    The ADS125H02 datasheet does a pretty good job of explaining the necessary steps to start conversions, identify when a conversion is ready (DRDY goes low), how to read data (RDATA command), and how to issue commands to change registers (WREG to the mux register). Moreover, conversion latency and start conversion delay are described in sections 9.4.1.3 and 9.4.1.4 respectively.

    Do you have any specific questions about how any of these things are completed? Is there anything unclear in the ADC datasheet?
