| RHF43B RAD-hardened precision bipolar single operational amplifier Features High immunity to radiations, 300kRad TID; SEL immune at 68MeV/cm/mg LET ions. Rail-to-rail input/output 8MHz gain bandwidth at 16V Stable for gain 5 Low input offset voltage: 100V typ Supply current: 2.2mA typ Operating from 3V to 16V Input bias current: 30nA typ ESD internal protection 2kV Latch-up immunity: 200mA Soon RHA QML-V qualified with smd n 5962-062xx NC IN IN + -VCC VDD 4 5 1 8 NC +VCC VCC OUT NC Ceramic Flat-8 Description The RHF43B is a precision bipolar operational amplifier available in hermetic 8-pin flat package and in die form. ln addition to its low offset voltage, rail-to-rail feature, 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 environment and in applications operating in harsh environments.

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+0.3V. 4. Short-circuits can cause excessive heating and destructive dissipation. 5. Rth are typical values. 6. Human body model: 100pF discharged through a 1.5k resistor between two pins of the device, done for all couples of pin combinations with other pins floating. Table 2.
