LM124A LM224A - LM324A LOW POWER QUAD OPERATIONAL AMPLIFIERS .. . .. .. . . WIDE GAIN BANDWIDTH / 1.3MHz LARGE VOLTAGE GAIN : 100dB VERY LOW SUPPLY CURRENT/AMPLI : 375µA LOW INPUT BIAS CURRENT : 20nA LOW INPUT OFFSET VOLTAGE : 3mV max. LOW INPUT OFFSET CURRENT : 2nA WIDE POWER SUPPLY RANGE : SINGLE SUPPLY : +3V TO +30V DUAL SUPPLIES : ±1.5V TO ±15V INPUT COMMON-MODE VOLTAGE RANGE INCLUDES GROUND ESD INTERNAL PROTECTION : 2kV DESCRIPTION These circuits consist of four independent, high gain, internally frequency compensated operational amplifiers. They operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible and the low power supply current drain is independent of the magnitude of the power supply voltage. All the pins are protected against electrostatic discharges up to 2000V (as a consequence, the input voltages must not exceed the magnitude of VCC+ or VCC-.)
