Stereo power amp, 24 volt supply

[johnr66]

Hi,
I'm looking for a chip amp that meets the following:
powered from a 24 volt (single) supply.
2 Channel
Ability to drive 4 Ohm loads.
low part count to keep costs down
fixed gain preferable (less parts)
Single ended (no BTL)

I'm thinking like a TDA1517, but with higher voltage supply that means higher power output.

Thanks!

TDA2040 will do it perfectly...just don t forget to add two 1N4004
(in reverse mode of course) from the amp pin output (pin 4) to supply rails
if you are to use this single power supply..

hii
with that 24volt single rail , i would suggest TPA3122 , dip16 package, Class D , simple to use and good out put 15 watt per channel , no heatsink requirements and single side board design,

Thanks for the replies. I'll probably try a class D in another project, but want analog for now.

Why clamping diodes on the TDA2040 in single supply, reduced power use?

noo its to do something with keep ing output capacitors charged or preventng dc from causing loud pops when powerd on , nothing for efficency jst safty and stabilty
