LOW POWER SINGLE OPERATIONAL AMPLIFIER

Description

The AS321 is a high gain and internally frequency compensated

operational amplifier specifically designed to operate from a single

power supply. Operation 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 V

= 5V

 Wide Power Supply Voltage:

 Single Supply: 3V to 36V

 Dual Supplies: ±1.5V to ±18V

 Wide Input Common Mode Voltage Range: 0V to V

-1.5V
