Description
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.
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 amplifiers. These characteristics coupled with a 1.5V/µs slew rate and a 400kHz bandwidth make the HA-5142 ideal for use in low power instrumentation, audio amplifier and active filter designs. The wide range of supply voltages (3V to 30V) also allow this amplifier 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.
This amplifier is available with industry standard pinouts which allow the HA-5142 to be interchangeable with most other dual operational amplifiers. For military grade product refer to the HA-5142/883 data sheet.
