TDA7295, 80W Audio Amplifier

Below is a 80W amplifier circuit is constructed by using a power IC TDA7295. With a very simple design, makes this circuit very easy to build. TDA7295 has many features to support your audio system, the most important is that the IC has very low distortion and very low noise feature.

The TDA7295 is a monolithic integrated circuit in Multiwatt15 package, intended for use as audio class AB amplifier in Hi-Fi field applications such as home theatre and topclass TV. The wide voltage range and to the high out current capability make the TDA7295 able to supply the highest power into both 4W and 8W 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.

10W Audio Amplifier circuit based on TDA1910

Simple and cheap, that's the advantage of this circuit. Although the output power is not high but audio quality is good, because TDA1910 has a very low noise feature. This circuit suitable for use as a student project.

About TDA1910:
The TDA1910 is a monolithic integrated circuit in MULTIWATT® package, intended for use in Hi-Fi audio power applications, as high quality TV sets.
The TDA 1910 meets the DIN 45500 (d = 0.5%) guaranteed output power of 10W when used at 24V/4W. At 24V/8W the output power is 7W min.
TDA1910 Features:

• muting facility
• protection against chip over temperature
• very low noise
• high supply voltage rejection
• low “switch-on” noise.
