Overview

The HS-OP470ARH and HS-OP470AEH are radiation hardened, monolithic quad operational amplifiers that provide highly reliable performance in harsh radiation environments. Excellent noise characteristics coupled with a unique array of dynamic specifications make these amplifiers well-suited for a variety of satellite system applications. Dielectrically isolated, bipolar processing makes these devices immune to single event latch-up. The HS-OP470ARH and HS-OP470AEH show almost no change in offset voltage after exposure to 100krad(Si) gamma radiation, with only a minor increase in current. Complementing these specifications is a post radiation open-loop gain in excess of 40kV/V. These quad operational amplifiers are available in an industry standard pinout, allowing for immediate interchangeability with most other quad operational amplifiers.
