AS321 Datasheet | BCD Semiconductor

Data Sheet LOW POWER SINGLE OPERATIONAL AMPLIFIER General Description The AS321 is a high gain and internally frequency pensated 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 patible with industry standard 321. The AS321 is available in SOT-23-5L packages. Features - - - - - - Excellent Phase Margin: 60 deg.
