Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.

Note 2: A heat sink may be required when the output is shorted indefinitely.

Note 3: Commercial parts are designed to operate over – 40

C to 85

°

C. Industrial grade parts

specified and tested over – 40

C are available on special request.

Consult factory.

Note 4: Input offset voltage is pulse tested and is exclusive of warm-up drift.

Note 5: Slew rate is measured between 

±

10V on an output swing of 

±

12V.

Note 6: FPBW = SR/2

.

Note 7: Differential Gain and Phase are tested in A

V

 = 2 with five amps in

series. Attenuators of 1/2 are used as loads (75

, 75

Ω

 and 499
