AVT2865 A

Class D amplifiers are very popular. Many manufacturers have in their offers specialized integrated circuits allowing for the construction of even several hundred audio amplifiers. Their main advantages are high efficiency (up to 95%) and low distortion. Unfortunately, this type of integrated circuits are difficult to get in Poland. This problem was omitted in the present kit using bridging topology and as controllers IR2113 systems. The output stage was designed on field-effect transistors. Taking into account their parameters, with the use of appropriate heat sinks, it is possible to achieve output power of up to 500W at a load of 8μm.

The device is especially recommended for demanding audiophiles-electronics

Selected parameters:

• mono power amplifier working in class D
• power output on radiators as in the picture about 100W
• layout of the saw voltage generator at 555
• 2V input voltage (for full control)
• power supply - 40Vdc
• printed circuit board and documentation included
