With TDA7294, you can use a simple cheap quality amplifier circuit with a single circuit, either Mono 200w or Stereo 2×100. TDA-7294 two-channel power amplifier with direct bridge connection (BTL) configurable.
TDA7294 is a highly innovative DMOS high power integrated amplifier circuit released by the famous European SGS-THOMSON ST Microelectronics in the 1990s.
Linear integrated power amplifiers and thick-film integrated amplifiers of the past have no raw, cold and harsh tones, and are widely used in the field of HI-FI.
TDA7294 released by ST has a wide operating voltage range ( VCC+VEE ) = 80V output power up to 100W and output current up to 10A It has good features and sound quality.
This powerful integrated can maintain a very low total harmonic distortion rate during continuous high power output. The peripheral circuit is simple and easy to understand, so the installation is simple and the success rate is very high.
The TDA7294 can be said to be low in price, but due to its excellent sound quality, it is widely used by famous Hi-End audio manufacturers such as Jeff Rowland in the United States and LINN in the United Kingdom.
As the output current is as high as 10A, the TDA7294 can also easily bridge the output power above 250W with bridging techniques! The original DATASHEET contains the circuit diagram of the standard and bridging methods.
As far as the author sees, there isn’t much difference. Why not design a bit on the original two channel board so you can simply connect the left and the two channels on the right quickly become bridged (BTL) mono.
To use TDA7294 Mono 200w, short circuit the R-IN Input and connect your speaker to L-SP Bridge + R-SP Bridge – terminals.

TDA7294 Europa sind bekannt ST SGS-THOMSON Microelectronics, das Unternehmen, das in 90 Jahren im Auftrag eines sehr DMOS innovativen Satzes gestartet wurde, diktiert die Erfolgsrate der Entlastung Road. Es hat den TDA-7294 mit einem breiten Spektrum an Betriebsspannung (VCC VEE) = 80V angekündigt. Der STDA-7294 ist mit einem breiten Spektrum an Betriebsspannung (VCC VEE) = 80V vertreten mehr Leistung bis zu 100W, die elektrische Ausgangsleistung von 10A von mehr Spektrum, kein Fehler und die Eigenschaften der Qualität Leistung! OP bei der Leistungsrate diktiert kontinuierliche Ausgabe und behält immer noch eine sehr niedrige totale harmonische Verzerrungsrate, Peripherieschaltung
