We are using AD9253 in our project. We are using following commands (via SPI) to power down Channels B,C &D & enable only Channel-A. After doing this, we still see some data on Channel-B,C &D, which means, it has not power down Channels-B.C &D.

Please let us know if we are doing anything wrong or there is an issue with the device (ADC).


Steps followed to power down only Channels-B,C &D.

  1. Write 0x05 with value of 0x0E.
  2. Write 0x22 with value of 0x01.


Waiting for response.
