The q denotes specifications which apply over the full temperature range. Note 1: A heat sink may be required when the output is shorted indefinitely. Note 2: 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 3: Input offset voltage is pulse tested and is exclusive of warm-up drift. Note 4: Slew rate is measured between ±10V on an output swing of ±12V. Note 5: FPBW = SR/2 πVP. Note 6: Differential Gain and Phase are tested in AV = 4 with five amps in series. Attenuators of 1/4 are used as loads (36.5 Ω, 110Ω and 249 Ω, 750Ω). |
