Need advice on DAC output buffer CMOS op-amps: AD8656 or OPA2365?

K3cT · 28th July 2010, 09:10 PM

Hi guys,

I am in a dilemma. I am currently tweaking a DIY DAC (AMB γ2) and it employs a CMOS, rail-to-rail, low voltage op-amp as its output buffer. The recommended options are AD8656 or OPA2365. Given your experience, which of these two options is the better performer?

I currently installed the AD8656 in the DAC but I suppose I'm willing to go the extra length to swap it with the OPA2365 should there be obvious improvements to be gained. I did a search before in Google and here but information regarding these op-amps' use as buffers is pretty scarce.

Thank you in advance!

On a 2nd thought it seems that this also fits in the DAC subforum so if you mods feel that this is off-topic here, perhaps you can move it there. My apologies.
