2.7V DC ELECTRICAL CHARACTERISTICS Unless otherwise noted, all min/max limits are guaranteed for TA = 25°C,
V+ = 2.7 V, V− = 0 V, VCM = V+/2, VO = V+/2 and RL > 1 MW. Typical specifications represent the most likely parametric norm.

6. Connected as voltage follower with input step from V− to V+. Number specified is the slower of the positive and negative slew rates.
7. Input referred, RL = 100 kW connected to V+/2. Each amp excited in turn with 1 kHz to produce VO = 3 VPP. (For Supply Voltages < 3 V,
VO = V+).
