DC ELECTRICAL CHARACTERISTICS (15V) (CONTINUED)

VV+ = +15V, VV– = 0V, VCM = 1.5V, VOUT = VV+/2; RL = 1 MΩ; TJ = +25°C; Note 1.

Conditions

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: RL connected to 7.5V. Sourcing: 7.5V ≤ VOUT ≤ 12.5V. Sinking: 2.5V ≤ VOUT ≤ 7.5V.

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