Low Power Single Operational Amplifier LM321N5 Low Power Single Operational Amplifier General Description The LM321N5 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. Features Wide supply voltage range -Single supply: 3V to 36V -Dual supplies: ±1.5V to ±18V Low input bias current: 20nA (typical) Low input offset voltage: 2mV (typical) Low supply current: 0.35mA at Vcc=5V Large voltage gain: 100dB (typical) Wide Input common mode voltage range: 0V to VCC-1.5V Excellent phase margin: 60 deg RoHS compliant and halogen free Applications Battery Charger Active Filters General Purpose Controllers, Instruments TAITRON COMPONENTS INCORPORATED www.taitroncomponents.com Tel: Fax: (800)-TAITRON (800)-824-8766 (800)-TAITFAX (800)-824-8329 (661)-257-6060 (661)-257-6415 Rev.
