Characterization and Modeling of the 709 Integrated Circuit Operational Amplifier in an Ionizing Radiation Environment

An empirical technique for simplified computer modeling of a 709 operational amplifier integrated circuit in an ionizing radiation environment is presented. The model makes use of an RLC network and a voltage-transfer curve to model the normal electrical operation of the 709. An additional voltage generator models the radiation response. Comparisons between the radiation response predicted by the model and observed radiation response are shown.
