TDA7266 Audio Amplifier Module

The only modifications to the bottom cover are the ventilation holes. 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.

According to the datasheet, the input impedance tds7266 the TDA is 30k ohms. Menu Products Explore our product portfolio. Notify me of follow-up comments by email. If you produce your own PCB for this amplifier td7266 that placement in mind.

The controls and connectors are what I had on hand.


The amp is powered by a 12V DC wall plug power supply. It requires few external components and should perform well given a reasonable PC layout.

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:. Who We Are Management. Product is in volume production 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. Rear View The controls and hda7266 are what I had on hand. In general, the wires are routed as they would be for any amplifier. Media Subscription Media Contacts. Product is in volume production Evaluation: Selectors Simulators and Models.
