Dual, 400khz, Ultra-low Power Operational Amplifier

The HA-5142 ultra-low power operational amplier provides AC and DC performance characteristics similar to or better than most general purpose ampliers while only drawing 1/30 of the supply current of most general purpose ampliers. In applications which require low power dissipation and good AC electrical characteristics, this device offers the industrys best speed/power ratio. The HA-5142 provides accurate signal processing by virtue of its low input offset voltage (2mV), low input bias current (45nA), high open loop gain (100kV/V) and low noise (20nV/Hz), for low power operational ampliers. These characteristics coupled with a 1.5V/s slew rate and a 400kHz bandwidth make the HA-5142 ideal for use in low power instrumentation, Audio amplier and active lter designs. The wide range of supply voltages (3V to 30V) also allow this amplier to be very useful in low voltage battery powered equipment. This device is also tested and guaranteed at both 15V and single ended +5V supplies. By Intersil Corporation
