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
μ
F electrolytic capacitor is connected close to pin 2.
