GENERAL DESCRIPTION
The TDA2616 and TDA2616Q are dual power amplifiers.
The TDA2616 is supplied in a 9-lead single-in-line (SIL9)
plastic power package (SOT131), while the TDA2616Q is
supplied in a 9-lead SIL-bent-to-DIL plastic power package
(SOT157). They have been especially designed for mains
fed applications, such as stereo radio and stereo TV.

FUNCTIONAL DESCRIPTION
The TDA2616 is a hi-fi stereo amplifier designed for mains
fed applications, such as stereo radio and TV. The circuit
is optimally designed for symmetrical power supplies, but
is also well-suited to asymmetrical power supply systems.
An output power of 2
×
12 W (THD = 0.5%) can be
delivered into an 8
Ω
load with a symmetrical power supply
of
±16
V. The gain is internally fixed at 30 dB, thus offering
a low gain spread and a very good gain balance between
the two amplifiers (0.2 dB).
A special feature is the input mute circuit. This circuit
disconnects the non-inverting inputs when the supply
voltage drops below
±6
V, while the amplifier still retains its
DC operating adjustment. The circuit features suppression
of unwanted signals at the inputs, during switch-on and
switch-off.
The mute circuit can also be activated via pin 2. When a
current of 300
µA
is present at pin 2, the circuit is in the
mute condition.
The device is provided with two thermal protection circuits.
One circuit measures the average temperature of the
crystal and the other measures the momentary
temperature of the power transistors. These control
circuits attack at temperatures in excess of +150
°C,
so a
crystal operating temperature of max. +150
°C
can be
used without extra distortion.
With the derating value of 2.5 K/W, the heatsink can be
calculated as follows:
at R
L
= 8
Ω
and V
P
=
±16
V, the measured maximum
dissipation is 14.6 W.
With a maximum ambient temperature of +65
°C,
the
thermal resistance of the heatsink is:

the maximum unloaded supply voltage is limited to 32 V
