TDA2611A Datasheet PDF Download

There are two manufacturers who are sharing the datasheet of the TDA2611A online. Namely, NXP (Philips, formerly) and UTC. You can download the TDA2611A datasheet pdf file using the link below.

TDA2611A Equivalent / Alternative ICs

To find an equivalent/alternative IC for the TDA2611A, it needs to have the following requirements:

  • VCC Range: 6v To 35v (or more)
  • Output Power: 4.5W (or more)

By applying the above specs to the filtering system on, I could easily find more than 5 alternative ICs to the TDA2611A. You can check it yourself here and select your desired specs.
