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.

APPLICATION SUGGESTION
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 100nFcapacitor connectedbetweensupply
pins and ground ;
- boucherot cell (0.1 to 0.2 µF + 1series) be-
tween outputs and ground or across the load.
With single supply operation, a resistor (1k)
between the output and supply pin can be
necessary for stability.
