HA-5142
April 1999 File Number 2909.4
Dual, 400kHz, Ultra-Low
Power Operational Ampliï¬er
The HA-5142 ultra-low power operational ampliï¬er provides
AC and DC performance characteristics similar to or better
than most general purpose ampliï¬ers while only drawing
1/30 of the supply current of most general purpose
ampliï¬ers. In applications which require low power
dissipation and good AC electrical characteristics, this
device offers the industryâs 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/âHz), for low power operational ampliï¬ers. 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 ampliï¬er and active ï¬lter
designs. The wide range of supply voltages (3V to 30V) also
allow this ampliï¬er 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 ampliï¬er is available with industry standard pinouts
which allow the HA-5142 to be interchangeable with most
other dual operational ampliï¬ers. For military grade product
refer to the HA-5142/883 data sheet.
