RL = 10 kâ¦, VO = 1.0 VPP

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 test conditions, see the Electrical Characteristics.

Note 2: Human body model, 1.5 kâ¦ in series with 100 pF.

Note 3: Applies to both single-supply and split-supply operation. Continuous short circuit operation at elevated ambient temperature can result in exceeding the

maximum allowed junction temperature of 150ËC.

Note 4: The maximum power dissipation is a function of TJ(Max), Î¸JA, and TA. The maximum allowable power dissipation at any ambient temperature is

PD = (TJ(Max) â TA)/Î¸JA. All numbers apply for packages soldered directly into a PC board.

Note 5: Typical values represent the most likely parametric norm.

Note 6: All limits are guaranteed by testing or statistical analysis.

Note 7: V+ = 3V, VCM = 1.5V and RL connected to 1.5V. For Sourcing tests, 1.5V â¤ VO â¤ 2.5V. For Sinking tests, 0.5V â¤ VO â¤ 1.5V.

Note 8: Connected as Voltage Follower with 1.0V step input. Number specified is the slower of the positive and negative slew rates.

Note 9: Input referred, V+ = 3V and RL = 100 kâ¦ connected to 1.5V. Each amp excited in turn with 1 KHz to produce VO = 2 VPP.
