Rad-Hard 120 MHz Low Power Single Opamp

The RHF310 is a very low power, high-speed operational amplifier. A bandwidth of 120 MHz is achieved while drawing only 400 µA of quiescent current. This low-power characteristic is particularly suitable for high-speed battery powered devices requiring dynamic performance. The RHF310 is a single operator available in a Flat-8S package which saves board space as well as providing excellent thermal performance.
