80W amplifier with the TDA 7294


Technical details:
input sensitivity 1.3V
input impedance 10K
bandwidth 16 Hz ..... 100KHz
Slew rate 10V/µs
output power (0,1%THD) 50W at 8 Ohm
82W at 4 Ohm
Signal to noise ratio 105 dBA
THD+N at 40W 0.002% (1kHz)
<0.04% (20....20kHz)

 

This is a high quality amplifier, unless you are a real audio freak who makes a fuzz about 0,01% harmonic distortion.
The TDA7294 is a widely used integrated Audio amplifier circuit made by SGS-Thomson.
