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.

Applications

■ Space probes and satellites ■ Defense systems ■ Scientific instrumentation ■ Nuclear systems NC +VCC NC OUT -VCC NC IN - IN + Ceramic Flat-8 VDD VCC NC +VCC NC OUT -VCC NC IN - IN + Ceramic Flat-8 VDD VCC

1 Absolute maximum ratings and operating conditions

Table 1. Absolute maximum ratings (AMR)

  1. All values, except differential voltage are with respect to network terminal.
  2. Differential voltages are the non-inverting input termi nal 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 c ause excessive heating and destructive dissipation.
  5. Human body model: 100pF discharged through a 1.5k Ω resistor between two pins of the device, done for

all couples of pin combinations with other pins floating. Table 2. Operating conditions
