FEATURES
GENERAL DESCRIPTION
·
Requires very few external components
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.
·
No switch-on/switch-off clicks
·
Input mute during switch-on and switch-off
·
Low offset voltage between output and ground
·
Excellent gain balance of both amplifiers
·
Hi-fi in accordance with IEC 268 and DIN 45500
·
Short-circuit proof and thermal protected
·
Mute possibility.

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.

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

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
