FUNCTIONAL DESCRIPTION

This hi-fi power amplifier is designed for mains fed applications. The device is intended for asymmetrical power supplies,

but a symmetrical supply may also be used. An output power of 6 watts (THD = 0,5%) can be delivered into an 8 W load

with an asymmetrical power supply of 24 V.

The gain is fixed internally at 30 dB. Internal gain fixing gives low gain spread.

A special feature of this device is a mute circuit which suppresses unwanted input signals during switching on and off.

Referring to Fig.4, the 100 m F capacitor creates a time delay when the voltage at pin 3 is lower than an internally fixed

reference voltage. During the delay the amplifier remains in the DC operating mode but is isolated from the non-inverting

input on pin 9.

Two thermal protection circuits are provided, one monitors the average junction temperature and the other the

instantaneous temperature of the power transistors. Both protection circuits activate at 150 ° C allowing safe operation to

a maximum junction temperature of 150

C without added distortion.

Note to the Ratings

For asymmetrical power supplies (at short-circuiting of the load) the maximum supply voltage is limited to V P = 28 V.

THERMAL RESISTANCE

HEATSINK DESIGN EXAMPLE

With derating of 8 K/W, the value of heatsink thermal resistance is calculated as follows:

given R L = 8

and V P = 24 V, the measured maximum dissipation is 4,1 W; then, for a maximum ambient temperature

of 60

C, the required thermal resistance of the heatsink is:
