Radiation Hardened Uncompensated,
High Slew Rate Operational Amplifier
The HS-2520RH is a radiation hardened monolithic
operational amplifier which delivers an unsurpassed
combination of specifications for slew rate, bandwidth and
settling time. This dielectrically isolated amplifier is designed
for closed loop gains of 3 or greater without external
compensation. In addition, this high performance component
also provides low offset current and high input impedance.
The 100V/µs (Min) slew rate and fast settling time of this
amplifier makes it an ideal component for pulse amplification
and data acquisition designs. To insure compliance with slew
rate and transient response specifications, all devices are
100% tested for AC performance characteristics over full
temperature. This device is a valuable component for RF
and video circuitry requiring wideband operation. For
accurate signal conditioning designs, the HS-2520RH
superior dynamic specifications are complemented by 25nA
(Max) offset current and offset voltage trim capability.
Specifications for Rad Hard QML devices are controlled
by the Defense Supply Center in Columbus (DSCC). The
SMD numbers listed here must be used when ordering.
Detailed Electrical Specifications for these devices are
contained in SMD 5962-95685. A “hot-link” is provided
on our homepage for downloading.
