OPA2132 and 2134

ctong · 14th May 2007, 07:57 PM

Has anyone compared OPA2132 with 2134 as output opamps? The former costs more than twice the latter.

Just personal opinion, but find the 2132 has more definition in the top end. Felt like there was a frequency bump mid-band in the 2134, as well as having slightly sizzly highs.

Sadly, have no quantitative way of measuring...

Also consider the 2888!

Is it opa2888? I cannot find it on TI's website.

How does it compare with 2132 or 2134?

The 2134 is an "audio" op-amp, meaning that it is a de-rated 2132. The 2132 has better specs and is felt by most who have heard them compared to sound slightly better. Personally, my hearing isn't good enough (or my circuits are bad enough) to hear the difference.
