Sink Current for AD7124-4 from AIN Pins

Hi SundarSingh1 ,

May we know your application and adc configuration for this? 

What do you mean by sink current? Are you pertaining to the currents that the ADC can accept, or is it the currents from your AIN pins? 

Thanks and regards,

Rod

Hi Rod

We are using the ADC for reading thermocouple(~10 -2.5mV ), we like to know the current that flows into Ain PIN or Input Impedance value 

Thanks

Hi Sundar,

The current that flows into AIN pin (Analog Input Current) depends on your configuration of the ADC power mode, buffer, and gain. You may refer to table 3 below from the datasheet (AD7124-4 (Rev.E) (analog.com)). 

Thanks and regards,
