ADS7953-Q1: Analog input maximum value

Yuya Shoji

Part Number: ADS7953-Q1

Hi team,

Could you tell me the analog input maximum value? In my understanding, this max value is 5V even in both range1 and range2. Ultimately, I'd like to check if this ADC can observe 12V signal directly.

Best Regards,

Hi Shoji,

The MAX input is -300mV to VA + 300mV. VA is limited to 7V so there is no way to directly apply a 12V input. You will need to attenuate your input signal.
