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

HEATSINK DESIGN EXAMPLE
Assume VP = 18 V; RL = 8 Ω; Tamb = 60 °C; Tc = 150 °C (max.); for a 4 W application, the maximum dissipation is approximately 2.5 W. The thermal resistance from junction to ambient can be expressed as:
Rth j-a = Rth j-tab + Rth tab-h + Rth h-a =
Tj max |
–Tamb max |
= |
150 –60 |
= |
36 K/W |
------------------------------------------ |
Pmax |
----------------------2.5 |
|||
|
|
|
|
Since Rth j-tab = 9 K/W and Rth tab-h = 1 K/W, Rth h-a = 36 − (9 + 1) = 26 K/W.
