2.5V DC ELECTRICAL CHARACTERISTICS Unless otherwise noted, all min/max limits are guaranteed for TA = 25°C, V+ = 2.5 V,
Vâ = 0 V, VCM = V+/2, VO = V+/2 and RL > 1 MW. Typical specifications represent the most likely parametric norm. Min/Max
specifications are guaranteed by testing, characterization, or statistical analysis.

2. Connected as voltage follower with input step from 0.5 V to 1.5 V. Number specified is the average of the positive and negative slew rates.
3. Input referred, RL = 100 kW connected to V+/2. Each amp excited in turn with 1kHz to produce VO = 3 VPP. For Supply Voltages < 3 V,
VO = V+.
