DESCRIPTIONThe TDA7294 is a monolithic integrated circuit in
Multiwatt15 package, intended for use as audio
class AB amplifier in Hi-Fi field applications
(Home Stereo, self powered loudspeakers, Top-
class TV). Thanks to the wide voltage range and
to the high out current capability it is able to sup-
ply the highest power into both 4Ω and 8Ω loads
even in presence of poor supply regulation, with
high Supply Voltage Rejection.
The built in muting function with turn on delay
simplifies the remote operation avoiding switching
on-off noises.

THERMAL DATA
ELECTRICAL CHARACTERISTICS (Refer to the Test Circuit VS = ±35V, RL = 8Ω, GV = 30dB; Rg = 50 Ω; Tamb = 25°C, f = 1 kHz; unless otherwise specified.
Note (*):MUSIC POWER CONCEPT
MUSIC POWER is the maximal power which the amplifier is capable of producing across the rated load resistance (regardless of non linearity)
1 sec after the application of a sinusoidal input signal of frequency 1KHz.
Note (**): Tested with optimized Application Board (see fig. 2)
Note (***): Limited by the max. allowable current.

Figure 2: P.C.B. and components layout of the circuit of figure 1. (1:1 scale)
Note:The Stand-by and Mute functions can be referred either to GND or -VS.
On the P.C.B. is possible to set both the configuration through the jumper J1.

APPLICATION SUGGESTIONS (see Test and Application Circuits of the Fig. 1)The recommended values of the external components are those shown on the application circuit of Fig-
ure 1. Different values can be used; the following table can help the designer.
(*) R1 = R3 FOR POP OPTIMIZATION
(**) CLOSED LOOP GAIN HAS TO BE ≥ 24dB
