To avoid instabilities and too high distortion, the input- and power ground must be separated as long as possible and connected together as close as

possible to the IC.

(1) This capacitor can be omitted if the 220 μF electrolytic capacitor is connected close to pin 2.

Fig.14 Test and application diagram.

For single-end application the output peak current may not exceed 100 mA; at higher output currents the short circuit

protection (MLC) will be activated.
