Abstract: NPN-input bipolar operational amplifiers LM741 were irradiated with 60Co γ-ray, 3 MeV protons and 10 MeV protons respectively at different biases to investigating the proton radiation response of the NPN-input operational amplifier. The comparison of protons with 60Co γ-rays showed that the proton radiation mainly induced ionization damage in LM741. Under different bias conditions, the radiation sensitivity is different; zero biased devices show more radiation sensitivity in the input biased current than forward biased devices. Supply current(±Icc) is another parameter that is sensitive to proton radiation, 60Co γ-ray, 3 MeV and 10 MeV proton irradiation would induce a different irradiation response in ±Icc, which is caused by different ionization energy deposition and displacement energy deposition of 60Co γ-ray, 3 MeV and 10 MeV proton irradiation.
