ELECTRICAL CHARACTERISTICS (continued)
(V
Typical values are at T
Note 1: All devices are 100% production tested at T
Note 2: The input offset voltage includes the effects of mismatches in the internal V
Note 3: For gain of 0.25V/V, the input common-mode range is -1V to V
Note 4: The input current of a CMOS device is too low to be accurately measured on an ATE and is typically on the order of 1pA.
Note 5: Parts are functional with f
