LOWDROP DUAL POWER OPERATIONAL AMPLIFIER
L2726October 1998
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
DESCRIPTIONThe L2726 is a monolithic integrated circuit in SO-20
package intended for use as power operational am-
plifiers 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 automative, etc.
The high gain and high output power capability pro-
vide superior performance whatever an operational
amplifier/power booster combination is required.
