what is the Max Single Supply voltage of a TDA7265 Amp IC

[RWood.5]

..

[Piranha]

First, there is not single supply option for these amplifiers. Second, the supply voltages ar clearly written in the datasheet.

Piranha..... this is in the date sheet, page 2 of 11 "clearly" says Single Supply application

The TDA7265 can also be operated with a single supply if you connect the output load (speakers) DC-free via capacitors. An example can be found in the data sheet, Figure 2.

The supply voltage can then be correspondingly high, i.e. 40V for the recommended range, but must never exceed 50V (data sheet, page 2: 25V-(-25V) = 50V).

If you use this voltage range, the output capacitors should also have a voltage rating of at least 50V, better 80V.

Hope that helps?

Thanks so much, that was the answer I was hoping for, just didn't know if being refrenced to ground that it would limit the max +25V.

Great!
