1 Low Power Single Operational Amplifier Low Power Single Operational Amplifier General Description The 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 Tel: (800)-TAITRON (800) (661) Fax: (800)-TAITFAX (800) (661) Page 1 of 11

Limits over the full temperature are guaranteed by design, but not tested in production. 3. Over the full input common-mode range 0V to VCC-1.5V (at +25 C ). 4. The input common-mode voltage of either input signal voltage should not be allowed to go negatively by more than 0.3V (at 25 C). The upper end of the common-mode voltage range is VCC-1.5V (at 25 C), but either or both inputs can go to +36V without damages, independent of the magnitude of the VCC. Page 4 of 11
