FUNCTIONAL DESCRIPTION

The TDA2615 is a hi-fi stereo amplifier designed for mains fed applications, such as stereo radio and stereo 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

×

6 W (THD = 0.5%) can be delivered into an 8

Ω

load with a symmetrical power supply of

±

12 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

µ

A 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 6 K/W, the heatsink can be calculated as follows: at R

L

= 8

Ω

and V

S dissipation is 7.8 W.

=

±

12 V, the measured maximum

With a maximum ambient temperature of +60

°

C, the thermal resistance of the heatsink is:

R th

=

150 –

7.8

60

– 6 = 5.5 K/W

The metal tab has the same potential as pin 5.

SOLDERING

Plastic single in-line packages

B Y DIP OR WAVE

The maximum permissible temperature of the solder is

260

°

C; this temperature must not be in contact with the joint for more than 5 s. The total contact time of successive solder waves must not exceed 5 s.

The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified storage maximum. If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit.

R EPAIRING SOLDERED JOINTS

Apply the soldering iron below the seating plane (or not more than 2 mm above it). If its temperature is below

300

°

C, it must not be in contact for more than 10 s; if between 300 and 400

°

C, for not more than 5 s.
