TPA6120 circuit request

kaushama · 22nd October 2005, 02:14 PM

Has anyone have a circuit design of Texas instruments TPA6120 in conjunction with OPA2134 as input buffer?

http://focus.ti.com/docs/prod/folder...tpa6120a2.html

It seems to be a really impressive dedicated headphone amp chip. Please post a circuit design diagram, if somebody has it.
Thanks in advance!

I'm not sure exactly what you're looking for, but Rod Elliott has a nice prototype headphone amp listed in his article
ESP -- High Speed Amplifiers in Audio     (shown about halfway down the page).

I should point out that it is based upon the THS6012 instead of the TPA6120, but you might find his application useful,
and perhaps find the answers you are seeking.

Best regards,
David

The THS6012 and TPA6120 is more or less the same part. It may be a case of taking different prices for different markets.
