Description
www.DataSheet.net/
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.
