LOW POWER SINGLE OPERATIONAL AMPLIFIER

AS321

Data Sheet

May. 2010 Rev. 1. 5

BCD Semiconductor Manufacturing Limited

General Description

The AS321 is a high gain and internally frequency

compensated

operational

amplifier

specifically

designed to operate from a single power supply. Opera-

tion from split power supply is also possible and the

low power supply current drain is independent of the

magnitude of the power supply voltages. Typical

applications include battery charger, active filters,

general purpose controllers and most conventional

operational amplifier circuits.

The AS321 is compatible with industry standard 321.

The AS321 is available in SOT-23-5 packages.

Features

·

Excellent Phase Margin: 60 deg.

·

Large Voltage Gain: 100dB (Typical)

·

Low Input Bias Current: 20nA (Typical)

·

Low Input Offset Voltage: 2mV (Typical)

·

Low Supply Current: 0.35mA at VCC=5V

·

Wide Power Supply Voltage:

Single Supply: 3V to 36V

Dual Supplies: ± 1.5V to ± 18V

·

Wide Input Common Mode Voltage Range: 0V to

VCC-1.5V

Applications

·

Battery Charger

·

Active Filters

·

General Purpose Controllers, Instruments
