DESCRIPTION
The L272 is a monolithic integrated circuits in Powerdip, Minidip and SO packages intended for use as power operational amplifiers in a wide range of applications including servo amplifiers and power supplies, compacts disc, VCR, etc. The high gain and high output power capability provide superior performance whatever an operational amplifier/power booster combination is required.
