HA-5142
FN2909.5
Dual, 400kHz, Ultra-Low
Power Operational Amplifier
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.
