Description The RHF43B is a precision bipolar operational amplifier available in a ceramic 8-pin flat package and in die form. ln addition to its low offset voltage, rail-to-rail feature and wide supply voltage, the RHF43B is designed for increased tolerance to radiation. Its intrinsic ELDRS-free rad-hard design allows this product to be used in space applications and in applications operating in harsh environments.

1. All values, except differential voltage are with respect to network terminal. 2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. 3. The magnitude of input and output terminal must never exceed VCC + 0.3 V. 4. Short-circuits can cause excessive heating and destructive dissipation. 5. Rth are typical values. 6. Human body model: 100 pF discharged through a 1.5 kΩ resistor between two pins of the device, done for all couples of pin combinations with other pins floating.
