Radiation Hardened, Very-Low Noise Quad Operational Amplifier

Support is limited to customers who have already adopted these products.

The HS-OP470ARH is a radiation hardened, monolithic quad operational amplifier that provides 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 shows 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. This quad operational amplifier is available in an industry-standard pinout, allowing for immediate interchangeability with most other quad operational amplifiers.
