OPA2132 and OPA2134

Other Parts Discussed in Thread: OPA2134, OPA2132

I need a high PSRR amplifier, and I found OPA2132 is a good one with high PSRR. But the price is too high, OPA2134 is cheaper than OPA2132 and the PSRR is the same as OPA2132, I know they are used for audio amplifiers. Can I use OPA2134 for general purpuse as fast speed signal amplify or OPA2134 is only for audio use?

Billy,

OPA2134 ac specs like PSRR are almost identical to OPA2132; therefore, you may use in your application OPA2134 instead of OPA2132.

so what is the difference between OPA2132 and OPA2134? I have used OPA2134 instead of OPA2132, but the performance is not as good as OPA2132,

Billy,

The main difference between OPAx132 and OPAx134 is in DC precision of the high grade of OPAx2132P/U and OPA2134 (e.g. max Vos of 0.5mV vs 2mV, respectively). In other words, OPAx132PA and OPAx132UA (standard grades) are equivalent to OPAx134, which does NOT have a high grade.
