Anybody play with these yet?

Or should this post be in Chip Amps?

BTW - it does list a high PSRR

It looks like it would be an interesting chip to work with (I don't like the TQFP package it comes in though).

It lists a high PSRR but that's only at 1kHz where that figure just so happens to be at its best (marketing strategy...). At 20kHz the PSRR is closer to -50dB instead of the -90dB at 1kHz. I also hate how everyone markets their stuff as 25/50W when that's at 10% THD+N...

It can be used without an output filter but it would radiate a lot of HF garbage, so it would be best to use a filter if you planned to make an amp based on this chip.

You can peruse spec sheets all day but that won't help you figure out how the thing will actually sound. If you're feeling adventurous take a stab at building one. That's what I'm doing, just with something else

I have a couple of these with me.
Has anyone used this ic i.e implemented it as an amplifier before?
OR
can someone design the pcb for this ic based on the application circuit in the datasheet pdf(http://pdfserv.maxim-ic.com/en/ds/MAX9709.pdf) .there is a evaluation kit also for this out here>>http://pdfserv.maxim-ic.com/en/ds/MAX9709EVKIT.pdf
the package that i have is THIN QFN, 56 lead.

How good is the max9709?

I´m working on the pcb design.

Hi sir,
can u provide me the schematics for your design, and can u just tell me how is the MAX9709 working, is it reliable as i'm about to design an amplifier out of those, so please provide me the data.

Thank you
