Description

The HS-OP470ARH is a radiation hardened, monolithic quad

operational amplifier that provides highly reliable performance

in harsh radiation environments. Its excellent noise characteris-

tics coupled with an unique array of dynamic specifications

make this amplifier well-suited for a variety of satellite system

applications. Dielectrically isolated, bipolar processing makes

this device immune to Single Event Latch-up.

The HS-OP470ARH shows almost no change in offset voltage

after exposure to 100K RAD(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.

Specifications for Rad Hard QML devices are controlled

by the Defense Supply Center in Columbus (DSCC).

SMD numbers must be used when ordering.

Detailed Electrical Specifications for this are contained

in SMD 5962-98533. A “hot-link” is provided on our

homepage with instructions for downloading.
