Description 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-8 package, saving board space as well as providing excellent thermal performance.
