The controls and connectors are what I had on hand. 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 in volume production 2.

It requires few external components and should perform well given a reasonable PC layout. The cutouts I made to the chassis are detailed on a couple of drawings:.

General terms and conditions. Use thermal compound between the TDA and the heat sink. Leave a Reply Cancel reply Your email address will not be published. In general, the wires are routed as they would be for any amplifier. Menu Products Explore our product portfolio.


MEMS Microphones evaluation tools 6: It also does not touch the chassis at any point. It takes a lot of heat. According to the datasheet, the input impedance of tda72666 TDA is 30k ohms. Product is under characterization. The only modifications to the bottom cover are the ventilation holes.

U1, the TDA, is installed after the heat sink pins are soldered. The chassis and bottom cover are painted with Krylon Satin Black spray tda72666 from Lowes. Not Recommended for New Design.

I had stock of some WIMA 2. Notify me of follow-up comments by email. I drilled the larger holes with a metric step drill examples.

The front panel is bamboo that was laser cut at ponoko.
