DESCRIPTION

The 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.
