HS-2520RH Data Sheet 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.
