(1)
Based on VREFT – VREFB = 1.0 V, varies proportional to the VREFT – VREFB value. AIN+ and AIN– inputs must always be greater than 0 V
and less than AVDD.
(2)
Clock pin is referenced to AGND and powered by AVDD.
(3)
Clock frequency can be extended to this range without degradation of performance.
