Rad-Hard 120 MHz Low Power Single Opamp

The RHF310, RHF310A device is a very low power, high-speed, single 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 mounted in a Flat-8 hermetic package with 3 mm leads (Flat-8S) and the RHF310A is mounted in a Flat-8 hermetic package with 8 mm leads (Flat-8).
