Data Sheet HA-5142 April 1999 File Number 2909.4 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.
