† 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.
