(8 + 8) 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. Minidip SO16 (Narrow) ORDERING NUMBERS : L272 (Powerdip)
