† _{Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and}
functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not
implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTE 1: VI(AIN) is AIN+ − AIN− range, based on VI(REFT)− VI(REFB) =1V. Varies proportional to the VI(REFT)− VI(REFB) value. Input common mode
voltage is recommended to be AVDD/2.
NOTE 2: The clock pin is referenced to AVSS and powered by AVDD.
NOTE 3: Clock frequency can be extended to this range without degradation of performance.
