L272
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
Powerdip
(8 + 8)
DES CRI P TI O N
The 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 SUGGESTION
NOTE
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 ;
- boucherotcell (0.1 to 0.2 µF + 1 Ω series) between
outputs and ground or across the load.
