LOWDROP DUAL POWER OPERATIONAL AMPLIFIERS
L2720/2/4November 1996
LOW DROP 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. LOW INPUT OFFSET VOLTAGE. GROUND COMPATIBLE INPUTS. LOW SATURATION VOLTAGE. THERMAL SHUTDOWN. CLAMP DIODE
DESCRIPTIONThe 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.

APPLICATION SUGGESTIONIn 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 connected between supply
pins and ground ; boucherot cell (0.1 to 0.2 μF + 1Ω series) be-
tween outputs and ground or across the load.
With single supply operation, a resistor (1kΩ)
between the output and supply pin can be
necessary for stability.
