L2720D

L2720D LOW DROP DUAL POWER OPERATIONAL AMPLIFIER s s s s s s s s s 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 DESCRIPTION The L2720D is a monolithic integrated circuits in SO16 package, intended for use as power operational amplifiers in a wide range of applications including servo amplifiers and power supplies. It is particularly indicated for driving, inductive loads, as motor and finds applications in compact-disc VCR automotive, etc. The high gain and high output power capability provide superior performance whatever an operational amplifier/power booster combination is required.
