Note 1: All limits guaranteed by testing or statistical analysis.

2: CMRR is determined as follows: The maximum ΔVOS over the VCM range is divided by the magnitude of

the VCM range. The measurement points are: VCM = VV– – 0.3V, (VV+ – VV–)/2, and VV+ + 0.3V.

3: Continuous short circuit may exceed absolute maximum TJ under some conditions.
