General terms and conditions. Product is in volume production. The PCB is relatively easy to assemble. Product is in volume production 2. In general, the wires are routed as tea7266 would be for any amplifier.

A PDF of the schematic can be downloaded here: Product is under characterization.


Computers and Peripherals Data Center. Who We Are Management.

The cutouts I made to the chassis are detailed on a couple of drawings: If you decide to recreate this chassis then you will need to adjust the size of the holes to match your parts. Currently you have JavaScript disabled. The diameters of the holes in the front and rear of the chassis conform to the components I used. However, in my opinion, 26dB is a perfectly reasonable gain setting for the intended use of this amplifier. Your email address will not be published.

I drilled the larger holes with a metric step drill examples.

The cutouts I made to the chassis are detailed on a couple of drawings:. It also does not touch the chassis at any point. Product is in volume production only to support customers ongoing production. Notify me of new posts by email.

The wire pairs carrying the input signals are twisted together. Selectors Simulators and Models. The signal wires are kept separate from the power and speaker wiring and the length of all wires are no longer than they have to be.


There are a lot of sharp edges. According to the TDA data sheet, this amplifier powered by 12 VDC should be capable of supplying approximately 3 Watts per channel into an 8 ohm load at around. If you produce your own PCB for this amplifier keep that placement in mind. Marketing proposal for customer feedback. Use thermal compound between the TDA and the heat sink.
