Dual, 400kHz, Ultra-Low
Power Operational Ampli鏗乪r
The HA-5142 ultra-low power operational ampli鏗乪r provides
AC and DC performance characteristics similar to or better
than most general purpose ampli鏗乪rs while only drawing
1/30 of the supply current of most general purpose
ampli鏗乪rs. In applications which require low power
dissipation and good AC electrical characteristics, this
device offers the industry鈥檚 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/鈭欻z), for low power operational ampli鏗乪rs. These
characteristics coupled with a 1.5V/碌s slew rate and a
400kHz bandwidth make the HA-5142 ideal for use in low
power instrumentation, audio ampli鏗乪r and active 鏗乴ter
designs. The wide range of supply voltages (3V to 30V) also
allow this ampli鏗乪r to be very useful in low voltage battery
powered equipment. This device is also tested and
guaranteed at both
鹵15V
and single ended +5V supplies.
This ampli鏗乪r is available with industry standard pinouts
which allow the HA-5142 to be interchangeable with most
other dual operational ampli鏗乪rs. For military grade product
refer to the HA-5142/883 data sheet.
