The HA-5142 ultra-low power operational amplifier provides AC and DC performance characteristics similar to or better than most general purpose amplifiers while only drawing 1/30 of the supply current of most general purpose amplifiers. In applications which require low power dissipation and good AC electrical characteristics, this device offers the industry’s best speed/power ratio.
