L272D013TR
DUAL POWER OPERATIONAL AMPLIFIER
L272July 2003
DUAL POWER OPERATIONAL AMPLIFIERS OUTPUT CURRENT TO 1 A. OPERATES AT LOW VOLTAGES. SINGLE OR SPLIT SUPPLY. LARGE COMMON-MODE AND DIFFEREN-
TIAL MODE RANGE. GROUND COMPATIBLE INPUTS. LOW SATURATION VOLTAGE. THERMAL SHUTDOWN
DESCRIPTIONThe L272 is a monolithic integrated circuits in Pow-
erdip, Minidip and SO packages intended for 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.

APPLICATION SUGGESTIONNOTE
In order to avoid possible instability occuring into fi-
nal stage the usual suggestions for the linear power
stages are useful, as for instance : layout accuracy ; a 100nF capacitor corrected between supply pins
and ground ; boucherot cell (0.1 to 0.2 μF + 1 Ω series) between
