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.
