L2722 STMicroelectronics

L2720/2/4 LOW DROP DUAL POWER OPERATIONAL AMPLIFIERS . OUTPUT CURRENT TO 1 A . OPERATES AT LOW VOLTAGES . SINGLE OR SPLIT SUPPLY .LARGE COMMON-MODE AND DIFFEREN- TIAL MODE RANGE . LOW INPUT OFFSET VOLTAGE . GROUND COMPATIBLE INPUTS POWERDIP (8 + 8) . LOW SATURATION VOLTAGE . THERMAL SHUTDOWN . CLAMP DIODE MINIDIP (Plastic) DESCRIPTION The L2720, L2722 and L2724 are monolithic inte- grated circuits in powerdip, minidip and SIP-9 pack- ages, intended for use as power operational ampli- fiers in a wide range of applications including servo amplifiers and power supplies. They are particularly indicated for driving, inductive SIP9 loads, as motor and finds applications in compact- disc VCR automotive, etc. ORDERING NUMBERS : L2720 (Powerdip) The high gain and high output power capability pro- L2722 (Minidip) vide superior performance whatever an operational L2724 (SIP9) amplifier/power booster combination is required.
