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 Ωload
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 µF 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.
RATINGS
Limiting values in accordance with the Absolute Maximum System (IEC 134)
Note to the Ratings
For asymmetrical power supplies (at short-circuiting of the load) the maximum supply voltage is limited to VP= 28 V.
If the total internal resistance of the supply (RS)≥4Ω, the maximum unloaded supply voltage is increased to 32 V.
For symmetrical power supplies the circuit is short-circuit proof to VP= ±21 V.

THERMAL RESISTANCE
HEATSINK DESIGN EXAMPLE
With derating of 8 K/W, the value of heatsink thermal resistance is calculated as follows:
given RL= 8 Ωand VP= 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:
Note: The metal tab (heatsink) has the same potential as pin 5 (GND).

Input mute circuit
The input mute circuit operates only during switching on and off of the supply voltage. The circuit compares the 1⁄2supply
voltage (at pin 3) with an internally fixed reference voltage (Vref), derived directly from the supply voltage. When the
voltage at pin 3 is lower than Vref the non-inverting input (pin 9) is disconnected from the amplifier. The voltage at pin 3
is determined by an internal voltage divider and the external 100 µF capacitor.
During switching on, a time delay is created between the reference voltage and the voltage at pin 3, during which the
input terminal is disconnected, (as illustrated in Fig.5).
