4W Audio Amplifier based TDA1013B schematic

About TDA1020B:
The TDA1013B is an integrated 4W audio power amplifier with DC volume control , encapsulated in a 9-lead single in-line (SIL) plastic package. The wide supply voltage range makes this circuit ideal for applications in mains and battery-fed apparatus such as television receivers and record players.

The DC volume control stage has a logarithmic control characteristic with a range of more than 80 dB; control is by means of a DC voltage variable between 2 and 6.5 V. The audio amplifier has a well defined open loop gain and a fixed integrated closed loop. This device requires only a few external components and offers stability and performance.

TDA1013B Features:

Few external components Wide supply voltage range Wide control range Pin compatible with TDA1013A Fixed gain High signal-to-noise ratio Thermal protection
