L2726

® L 2726 LOW DROP DUAL POWER OPERATIONAL AMPLIFIER . . . . . . . . . OUTPUT CURRENT TO 1 A OPERATES AT LOW VOLTAGES SINGLE OR SPLIT SUPPLY LARGE COMMON-MODE AND DIFFERENTIAL MODE RANGE LOW INPUT OFFSET VOLTAGE GROUND COMPATIBLE INPUTS LOW SATURATION VOLTAGE THERMAL SHUTDOWN CLAMP DIODE SO20 (12 + 4 + 4) ORDERING NUMBER : L2726 DESCRIPTION The L2726 is a monolithic integratedcircuit in SO-20 package intended for use as power operationalamplifiers in a widerangeof applicationsincludingservo amplifiers and power supplies. It is particularly indicatedfor driving inductive loads, as motor and finds applications in compact-disc VCR automative, etc. PIN CONNECTION (top view) The high gain and high output power capability provide superior performance whatever an operational amplifier/power booster combination is required.
