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, but
are not tested nor guaranteed beyond 0°C to 70°C. Industrial grade parts
specified and tested over –40°C to 85°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/2Ï€VP.
Note 7: Differential Gain and Phase are tested in AV = 4 with five amps in
series. Attenuators of 1/4 are used as loads (36.5Ω, 110Ω and
249Ω, 750Ω).
