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 100nF capacitor connected between supply
pins and ground ;
Note :
Servocontrol for Compact-disc
Bidirectional DC Motor Control with P Compatible Inputs
The input voltage level is compatible with L291 (8 - BIT D/A converter)

boucherot cell (0.1 to 0.2 F + 1 series) 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.
