HS-OP470ARH
February 1998
Radiation Hardened, Very Low Noise
Quad Operational Amplifier
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.
