AS321KTR-E1

AS321KTR-E1 is a low-power, high-gain and internally frequency compensated operational amplifier specifically designed to operate from a single power supply. Operation from a split power supply is also possible and the low power supply current drain is independent of the magnitude of the power supply voltages. The AS321 is compatible with the industry standard 321. Typical applications include battery chargers, active filters, general-purpose controllers and most conventional operational amplifier circuits.
