® LM2902 LOW POWER QUAD OPERATIONAL AMPLIFIERS . . . . . . . WIDE GAIN BANDWIDTH : 1.3MHz INPUT COMMON-MODE VOLTAGE RANGE INCLUDES GROUND LARGE VOLTAGE GAIN : 100dB VERY LOW SUPPLY CURRENT/AMPLI : 375µA LOW INPUT BIAS CURRENT : 20nA LOW INPUT OFFSET CURRENT : 2nA WIDE POWER SUPPLY RANGE : SINGLE SUPPLY : +3V TO +30V DUAL SUPPLIES : ±1.5V TO ±15V N DIP14 (Plastic Package) D SO14 (Plastic Micropackage) DESCRIPTION This circuit consists of four independent, high gain, internally frequency compensated operational amplifiers which were designed specifically for automotive and industrial control systems. It operates 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.
