L165
3A POWER OPERATIONAL AMPLIFIER
OUTPUT CURRENT UP TO 3A
LARGE COMMON-MODE AND DIFFERENTIAL
MODE RANGES
SOA PROTECTION
THERMAL PROTECTION
± 18V SUPPLY
DESCRIPTION
The L165 is a monolithic integrated circuit in
Pentawatt® package, intended for use as power
operational amplifier in a wide range of applica-
tions, including servo amplifiers and power sup-
plies. The high gain and high output power
capability provide superiore performance wherever
an operational amplifier/power booster combina-
tion is required.
