TDA – 7 W + 7 W dual bridge amplifier – STMicroelectronics

Product is in design stage Target: The cutouts I made to the chassis are detailed on a couple of drawings:. The wire pairs carrying the input signals are twisted together.

The cutouts I made to the chassis are rda7266 on a couple of drawings: No availability reported, please contact our Sales office. In general, the wires are routed as they would be for any amplifier.

The chassis and bottom cover are painted with Krylon Satin Black spray paint from Lowes. Free Sample Add to cart.

I had stock of some WIMA 2. 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. Resources Technical Documentation Product Specifications.

There are a lot of sharp edges. However, in my opinion, 26dB is a perfectly reasonable gain setting for the intended use of this amplifier.

If you decide to recreate this chassis then you will need to adjust the size of the holes to match your parts. Product is in volume production Evaluation: The ground planes for power common and signal common on the PCB are kept separate except for the link that is just below the negative lead of C3 on the bottom side of the PCB.

Use thermal compound between the TDA and the heat sink. 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.

Product is under characterization.

The only modifications to the bottom cover are the ventilation holes. Td7a266 diameters of the holes in the front and rear of the chassis conform to the components I used.

Building this amplifier was a fun project not withstanding the deburring process and, in my opinion, produced a nice looking, and nice sounding little amplifier. A PDF of the schematic can be downloaded here: PDFs of the chassis modification drawings that contain full size templates are here: The PCB is relatively easy to assemble. Your email address will not be published. Who We Are Management. I doubt there is a human alive that can perceive the difference, but it was an easy change.

The amp is powered by a 12V DC wall plug tda2766 supply. The toughest part is soldering the tdx7266 mounting pins on the heat sink. Notify me of follow-up comments by td7266. I used ground planes here instead of the generally accepted practice of running independent traces to a star ground.

Cloud Components and Modules. Leave tfa7266 Reply Cancel reply Your email address will not be published. According to the datasheet, the input impedance of the TDA is 30k ohms.

Product is in volume production only to support customers ongoing production. Not Recommended for New Design. They theoretically work with the ventilation holes in the chassis to allow some airflow across the TDA heat tda726.

U1, the TDA, is installed after the heat sink pins are soldered. It requires few external components and should perform well given a reasonable PC layout. It also does not touch the chassis at any point.
