5V AC Electrical Characteristics
Unless otherwise specified, all limits guaranteed for T J = 25˚C, V+ = 5V, V− = 0V, VCM = 2.0V, VO = V+/2 and R L > 1 MΩ.
Boldface limits apply at the temperature extremes.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is in-
tended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical Characteristics.
Note 2: Human body model, 1.5 kΩ in series with 100 pF. Machine model, 0Ω in series with 200 pF.
Note 3: Shorting output to V+ will adversely affect reliability.
Note 4: Shorting output to V- will adversely affect reliability.
Note 5: The maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any ambient temperature is
P D = (TJ(max)–TA)/θJA. All numbers apply for packages soldered directly into a PC board.
Note 6: Typical values represent the most likely parametric norm.
Note 7: All limits are guaranteed by testing or statistical analysis.
Note 8: RL is connected to V -. The output voltage is 0.5V ≤ VO ≤ 4.5V.
Note 9: Connected as voltage follower with 3V step input. Number specified is the slower of the positive and negative slew rates.
Note 10: All numbers are typical, and apply for packages soldered directly onto a PC board in still air.
