The following a circuit of 80W audio amplifier is using by IC TDA7295. The circuit very simple and will be easy to build. TDA7295 has many features to support your audio system, the most important is that the IC has wide voltage range, very low distortion and very low noise feature.
TDA7295 IC Pinning- The TDA7295 IC must be fitted with adequately sized heat sinks.
- Power supply voltage should not exceed 40V
- Connect a 50K POT in series with the input as volume control if you need. Not shown in circuit diagram.
The TDA7295 is a monolithic integrated circuit in Multiwatt 15 package, intended for use as audio class AB amplifier in Hi-Fi field applications (Home Stereo, self powered loudspeakers, Topclass TV). Thanks to the wide voltage range and to the high out current capability it is able to supply 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.
