2x25W at 4 Ohm TDA7492 Class-D Audio Amplifier Board Only
I'm building a portable boombox and the problem I am running into is finding a battery that can power this. Does anyone know a solution to battery power this amp and the battery not be an acid battery. I was hoping for something like a LiPo battery?
how would I wire in the Input signal? there is the J1 box that has 8 holes between the 2 RCA inputs and it looks like you connect the 1 channel into side, then hook in the other channel to the other side and ground wires into the middle 2 spots?
What is the input impedance of this amp and drive requirements? Can it be driven from the headphone output of a communications receiver without any padding?
Would a 15V 1.4A power supply work with this amp? I'm not sure that 1.4A is enough.
Yes. I have that adapter. The fellows 15v it's a buyout special. It's rated 1.4 but it actually puts out 2.5 amps at 15v and something like 3 or so at 14v .yeah it works good.

The amp pictured has a heat-sink, yet the description indicates it doesn't need one. Is there a heat-sink installed on the board as shown?
Yes this does include a mounted heat sink as pictured. I will have the copy fixed.
