Title: Grind customs Chimera
Post by: LaceSensor on September 23, 2012, 12:17:02 PM
Hi

Can I use an LT1054 charge pump? I have a bunch, but dont have the SCPA of the 1044, only a CPA chip which think will add noise...

Thanks for advice

The CPA will make noise, but the LT1054 should work fine from what i've read, but i never tried.

If it does'nt work with the LT, let me know and i'll send you a 7660SCPA ;)

Edit: Thinking of it.........i need an LT1054, would you make a trade with me?

The LT1054 works fine, just remember to clip pin 1

Hi

Easier for me to cut pin one, but cheers for the offer.

Just sorting through and starting some of my pcb's and noticed the chimera white is v2 and seems a little different
than the most current v3  [ I also seem to have a black v1 pcb as well ]
I'll keep looking but can anyone email me the correct docs ?  tia regards Greg okgb
