TDA1521Q  
2 x 12 W hi-fi audio power amplifier  
FUNCTIONAL DESCRIPTION  
This hi-fi stereo power amplifier is designed for mains fed applications. The circuit is designed for both symmetrical and  
asymmetrical power supply systems. An output power of 2 × 12 watts (THD = 0,5%) can be delivered into an 8 load  
with a symmetrical power supply of ± 16 V.  
The gain is fixed internally at 30 dB. Internal gain fixing gives low gain spread and very good balance between the  
amplifiers (0,2 dB).  
A special feature of this device is a mute circuit which suppresses unwanted input signals during switching on and off.  
Referring to Fig.13, 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 amplifiers remain in their DC operating mode but are isolated from the  
non-inverting inputs on pins 1 and 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  
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 (Ri) > 4 , the maximum unloaded supply voltage is increased to 32 V.

THERMAL RESISTANCE  
From junction to case

HEATSINK DESIGN EXAMPLE  
With derating of 2,5 K/W, the value of heatsink thermal resistance is calculated as follows:  
given RL = 8 and VP = ±16 V, the measured maximum dissipation is 14,6 W; then, for a maximum ambient temperature  
of 65 °C, the required thermal resistance of the heatsink is  
150 65

APPLICATION INFORMATION  
Input mute circuit  
The input mute circuit operates only during switching on and off of the supply voltage. The circuit compares the 1/2 supply  
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 inputs (pins 1 and 9) are 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.3).

The device may be mounted up to the seating plane, but  
the temperature of the plastic body must not exceed the  
specified maximum storage temperature (Tstg max). 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.  
SOLDERING  
Introduction  
There is no soldering method that is ideal for all IC  
packages. Wave soldering is often preferred when  
through-hole and surface mounted components are mixed  
on one printed-circuit board. However, wave soldering is  
not always suitable for surface mounted ICs, or for  
printed-circuits with high population densities. In these  
situations reflow soldering is often used.  
Repairing soldered joints  
Apply a low voltage soldering iron (less than 24 V) to the  
lead(s) of the package, below the seating plane or not  
more than 2 mm above it. If the temperature of the  
soldering iron bit is less than 300 °C it may remain in  
contact for up to 10 seconds. If the bit temperature is  
between 300 and 400 °C, contact may be up to 5 seconds.  
This text gives a very brief insight to a complex technology.  
A more in-depth account of soldering ICs can be found in  
our “IC Package Databook” (order code 9398 652 90011).  
Soldering by dipping or by wave  
The maximum permissible temperature of the solder is  
260 °C; solder at this temperature must not be in contact  
with the joint for more than 5 seconds. The total contact  
time of successive solder waves must not exceed  
5 seconds.
