TDA7266 Audio Amplifier Module

MEMS Microphones evaluation tools 6: Not Recommended for New Design. Notify me of follow-up comments by email. I doubt there is a human alive that can perceive the difference, but it was an easy change. 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. 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.

It also does not touch the chassis at any point. No commitment taken to produce Proposal: For this application, the ground planes appear to work well. Free Sample Add to cart.

According to the datasheet, the input impedance of the TDA is 30k ohms. Product is in design feasibility stage. I drilled the larger holes with a metric step drill examples. There are a lot of sharp edges. Use thermal compound between the TDA and the heat sink. Leave a Reply Cancel reply Your email address will not tda266 published. The cutouts I made tdda7266 the chassis are detailed on a couple of drawings:.

Your email address will not be published. General terms and conditions. The amp is powered by a 12V DC wall plug power supply. I used ground planes here instead of the generally accepted practice of running independent traces to a star ground.

If you decide to recreate this chassis then you will need to adjust the size of the holes to match your parts. The cutouts I made to the chassis are detailed on a tdw7266 of drawings: Doing so will damage the TDA It takes a lot of heat. Product is in design stage Target: I had stock of some WIMA 2.

I found that deburring the holes on the inside of the chassis was a difficult and nightmarish experience. Building this amplifier was a tdz7266 project not withstanding the deburring process and, in my opinion, produced a nice looking, and nice sounding tea7266 amplifier.

The front panel is bamboo that was laser cut at ponoko. There is nothing especially critical concerning the wiring inside the chassis.

Resources Technical Documentation Product Specifications. The wire pairs carrying the input signals are twisted together.

Tdda7266 PCB is relatively easy to assemble. Cloud Components and Modules. If you produce your own PCB for this amplifier keep that placement in mind.
