DESCRIPTION

The L2720, L2722 and L2724 are monolithic inte- grated circuits in powerdip, minidip and SIP-9 pack- ages, intended for use as power operational ampli- fiers in a wide range of applications including servo amplifiers and power supplies. They are particularly indicated for driving, inductive loads, as motor and finds applications in compact- disc VCR automotive, etc. The high gain and high output power capability pro- vide superior performance whatever an operational amplifier/power booster combination is required.
