1 This is a functional specification. Amplifier bandwidth decreases when the input common-mode voltage is driven in the range ((V+) − 1 V) to V+. Common-mode error

voltage is typically less than 5 mV with the common-mode voltage set at 1 V below the positive supply.

2 V

OL − VEE is defined as the difference between the lowest possible output voltage (VOL) and the negative voltage supply rail (VEE). VCC − VOH is defined as the difference

between the highest possible output voltage (VOH) and the positive supply voltage (VCC).
