N DIP14 (Plastic Package) (for more accurate applications, use the equivalent parts LM124A-LM224A-LM324A which feature 3mV max) D SO14 (Plastic Micropackage) LOW INPUT OFFSET CURRENT : 2nA WIDE POWER SUPPLY RANGE : SINGLE SUPPLY : +3V TO +30V DUAL SUPPLIES : ±1.5V TO ±15V P TSSOP14 (Thin Shrink Small Outline Package) ORDER CODES 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.
