The diameters of the holes in the front and rear of the chassis conform to the components I used. The chassis and bottom cover are painted with Krylon Satin Black spray paint from Lowes. However, in my opinion, 26dB is a perfectly reasonable gain setting for the intended use of this amplifier. Tda7266 is nothing especially critical concerning the wiring inside the chassis.
U1, the TDA, is installed after the heat sink pins are soldered. A PDF of the schematic can be downloaded here: No availability reported, please contact our Sales office. Cloud Components and Modules. Not Recommended for New Design. The amp is powered by a 12V DC wall plug power supply. Product is in volume production 2. I found that deburring the holes on the inside of the chassis was a difficult and nightmarish experience.

Marketing proposal for customer feedback. Media Subscription Media Contacts. The cutouts I made to the chassis are detailed on a couple of drawings:.
I drilled the larger holes with a metric step hda7266 examples. The toughest part is soldering the two mounting pins on the heat sink. Doing so will damage the TDA Selectors Simulators and Models.

They theoretically work with the ventilation holes in the chassis to allow some airflow across the TDA tda7626 sink. ST Code of Conduct Blog. The controls and connectors are what I had on hand. Please contact our sales support for information on specific devices.
According to the datasheet, the input impedance of the TDA is 30k ohms. In general, the wires are routed as they would be for any amplifier.
