DESCRIPTION

The L272 is a monolithic integrated circuits in Pow- erdip, Minidip and SO packagesintendedfor use as power operational amplifiers in a wide range of ap- plications including servo amplifiers and power sup- plies, compacts disc, VCR, etc. The high gain and high output power capability pro- vide superior performance whatever an operational amplifier/power booster combination is required.
