AS321 LOW POWER SINGLE OPERATIONAL AMPLIFIER Description Pin Assignments The AS321 is a high gain and internally frequency compensated operational amplifier specifically designed to operate from a single (Top View) power supply. Operation from split power supply is also possible and the low power supply current drain is independent of the magnitude of INPUT + 1 5 V the power supply voltages. Typical applications include battery CC charger, active filters, general purpose controllers and most conventional operational amplifier circuits. V EE 2 The AS321 is compatible with industry standard 321. INPUT - 3 4 OUTPUT The AS321 is available in SOT25 package. SOT25 Features Excellent Phase Margin: 60 deg. Applications Large Voltage Gain: 100dB (Typical) Battery Charger Low Input Bias Current: 20nA (Typical) Active Filters Low Input Offset Voltage: 2mV (Typical) General Purpose Controllers, Instruments Low Supply Current: 0.35mA at V = 5V CC 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 CC Lead-Free Packages: SOT25 Totally Lead-Free RoHS Compliant (Notes 1 & 2) Lead-Free Packages, Available in Green Molding Compound: SOT25 Totally Lead-Free & Fully RoHS Compliant (Notes 1 & 2) Halogen and Antimony Free.
