The HS-5104ARH, HS-5104AEH 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-5104ARH, HS-5104AEH 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 40k.These quad operational amplifiers are available in an industry standard pinout, allowing for immediate interchangeability with most other quad operational amplifiers.
