hi all,

 

I had a problem with AD7294 chip.

1.ADC reading and DAC writing is not correct i mean its not working (ADC 0v(always),DAC 43mV (always))

2.It was working fine till yesterday since long time of development.

3.I checked configuring register(Setting DAC/ADC reference to 2.2v ) after code running,power to chip etc.

4.Wave forms and code commands to chip are proven  and is working with other modules.

5.Is there any way to check the hardware stability of chip before taking it off.

 

Regards
