INTEGRATED CIRCUITS DATA SHEET TDA1013B 4 W audio power amplifier with DC volume control July 1994 Product specification File under Integrated Circuits, IC01 Philips Semiconductors Product specification 4 W audio power amplifier with TDA1013B DC volume control GENERAL DESCRIPTION The TDA1013B is an integrated audio amplifier circuit 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 defi
