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 k
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 150C.
Note 4: The maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(max)
-TA)/θJA. 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: Connected as voltage follower with 1.5V step input. Number specified is the slower of the positive and negative slew rates. V+ = 3V and RL = 150 con-
nected to 1.5V. Amp excited with 1 kHz to produce VO = 1.5 VPP.
Note 8: Connected as Voltage Follower with 4.0V step input. Number specified is the slower of the positive and negative slew rates. V+ = 5V and RL = 150 con-
nected to 2.5V. Amp excited with 1 kHz to produce VO = 4VPP.
Note 9: Connected as Voltage Follower with 4.0V step input. Number specified is the slower of the positive and negative slew rates. V+ = 5V, V = 5V and
RL = 150 connected to 0V. Amp excited with 1 kHz to produce VO = 4VPP.
Note 10: Differential gain and phase measured with a 4.5 MHz signal into a 150
load, Gain = +2.0, between 0.6V and 2.0V output.
