TDA1013B
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 defined open loop gain and a fixed integrated closed loop. This device requires only a few
external components and offers stability and performance.
