They theoretically work with the ventilation holes in the chassis to allow some airflow across the TDA heat sink. Contacts Learning Longevity Commitment. Please contact our sales support for information on specific devices.

No commitment taken to produce Proposal: The wire pairs carrying the input signals are twisted together. Communications Equipment, Tda72266 and Peripherals. 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.

Product is in design stage Rda7266 It requires few external components and should perform well given a reasonable PC layout.


The controls and connectors are what I had on hand. Currently you have JavaScript disabled. Marketing proposal for customer feedback. I used ground planes here instead of the generally accepted practice of running independent traces to a star ground. If you produce your own PCB for this amplifier keep that placement in mind. There are a lot of sharp edges.

TDA7266 Low Power Stereo Amplifier

It takes a lot of heat. Product is under characterization. MEMS Microphones evaluation tools 6: General terms and conditions.

Resources Technical Documentation Product Specifications. The toughest part is soldering the two mounting pins on the heat sink.

Ta7266 Simulators and Models. No commitment taken to design or produce NRND: 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.

I doubt there is a human alive that can perceive the difference, but it was an easy change. Distributor Name Region Stock Min.

However, in my opinion, 26dB is a perfectly reasonable gain setting for the intended use of this amplifier. A PDF of the schematic can be downloaded here: 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.

Computers and Peripherals Data Center. Cloud Components and Modules. I found that deburring the holes on the inside of the chassis was a difficult and nightmarish experience. Notify me of new posts by email. The cutouts I made to the chassis are detailed on a couple of drawings: The PCB is relatively easy to assemble. Who We Are Management. 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.


There is nothing especially critical concerning the wiring inside the chassis.

I drilled the larger holes with a metric step drill examples. Rear View The controls and connectors are what I tra7266 on hand. The front panel is tdw7266 that was laser cut at ponoko. ST Code of Conduct Blog. Product is in volume production only to support customers ongoing production. No availability reported, please contact our Sales office. The chassis and bottom cover are painted with Krylon Satin Black spray paint from Lowes.

For this application, the ground planes appear to work well.
