6 W hi-fi audio power amplifier TDA2613
GENERAL DESCRIPTION
The TDA2613 is a hi-fi audio power amplifier encapsulated in a 9-lead SIL plastic power package. The device is
especially designed for mains fed applications (e.g. tv and radio).
Features
• Requires very few external components
• Input muted during power-on and off
(no switch-on or switch-off clicks)
• Low offset voltage between output and ground
• Hi-fi according to IEC 268 and DIN 45500
• Short-circuit-proof
• Thermally protected.

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 Ω 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 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.

Note to the Ratings
For asymmetrical power supplies (at short-circuiting of the load) the maximum supply voltage is limited to V
= 28 V.
P
If the total internal resistance of the supply (RS) ≥ 4 Ω, the maximum unloaded supply voltage is increased to 32 V.
For symmetrical power supplies the circuit is short-circuit proof to VP = ± 21 V.
