A Product Line of Diodes Incorporated 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 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. INPUT + 1 VEE 2 The AS321 is compatible with industry standard 321. INPUT - 3 (Top View) 5 VCC 4 OUTPUT The AS321 is available in SOT-23-5 packages.

The input common-mode voltage of either input signal voltage should not be allowed to go negatively by more than 0.3V (at +25oC). The upper end of the common-mode voltage range is VCC-1.5V (at +25oC), but either or both inputs can go to +36V without damages, independent of the magnitude of the VCC.
