Product specification

3 W mono BTL audio amplifier with DC
volume control

TDA7056AT

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.

Fig.14 Test and application diagram.

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.
