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

Ω in series with 100 pF.

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

mum allowed junction temperature of 150˚C. Output current in excess of ±30 mA over long term may adversely affect reliability.

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: V+ = 3V, VCM = 0.5V. For sourcing and sinking, 0.5V ≤ VO ≤ 2.5V.

Note 8: V+ = 3V. Connected as Voltage Follower with 2V step input, and output is measured from 0.8V to 2.2V. Number specified is the slower of the positive or nega-

tive slew rates.

Note 9: Input referred, V+ = 10V, and RL = 100 kΩ connected to 5V. Each amp excited in turn with 1 kHz to produce VO = 2VPP.

Note 10: V+ = 10V. Connected as voltage follower with 8V step Input, and output is measured from 2V to 8V. Number specified is the slower of the positive or nega-

tive slew rates.

Note 11: Limiting input pin current is only necessary for input voltages that exceed absolute maximum input voltage ratings.

Note 12: Guaranteed limits are dictated by tester limitations and not device performance. Actual performance is reflected in the typical value.

Note 13: CMRR+ and CMRR− are tested, and the number indicated is the lower of the two values. For CMRR+,V+/2 < VCM < V

+ for 1.8V, 2.2V, 3V, 5V, and 10V.

For CMRR−,0 < VCM < V

+/2 for 3V, 5V and 10V. For 1.8V and 2.2V, 0.25 < V

CM < V

+ −0.3.

Note 14: V+ = 10V, VCM = 0.5V. For Sourcing tests, 1V ≤ VO ≤ 5V. For Sinking tests, 5V ≤ VO ≤ 9V.
