at 16 V loaded supply in mains-fed applications. The maximum permissible supply
voltage of 24 V makes this circuit very suitable for d.c. and a.c. apparatus, while the very low applicable supply voltage
of 3,6 V permits 6 V applications. Special features are:
·
W
single in-line (SIL) construction for easy mounting
·
separated preamplifier and power amplifier
·
high output power
·
thermal protection
·
high input impedance
·
low current drain
·
limited noise behaviour at radio frequencies

The TDA1011 is a monolithic integrated audio amplifier circuit in a 9-lead single in-line (SIL) plastic package. The device
is especially designed for portable radio and recorder applications and delivers up to 4 W in a 4 W load impedance. The
device can deliver up to 6 W into 4

HEATSINK DESIGN
Assume V P = 12 V; R L = 4 W ; T amb = 60 ° C maximum; P o = 3,8 W.
The maximum sine-wave dissipation is 1,8 W.
The derating of 10 K/W of the package requires the following external heatsink (for sine-wave drive):
R th j-a = R th j-tab + R th tab-h + R th h-a = = 50 K/W.
Since R th j-tab = 10 K/W and R th tab-h = 1 K/W, R th h-a = 50
150 60
-
(10 + 1) = 39 K/W.
