[sdiy] Op Amp selection criteria

[Justin Owen]

Hello,

I'm looking for advice on selecting some good op-amps for the following purposes:

1) VCO Integrator (both Tri and Saw core)
2) Buffer/Voltage Follower (to buffer the out of a DAC which in turn is being fed by a micro doing Lin to Exp conversion - so ultra low offset/precision is vital)
3) Audio frequency amplifier (possibly both Inverting and Non-Inverting)

I don't necessarily need the best  - but I do want to try some 'good ones. I've been using the parameter search at TI and AD and there's loads of parameters I don't really understand - so I guess my question is...

...are there any main/general parameters for choosing op amps that would be best suited for the above purposes? e.g. get the lowest/highest/fastest value for parameter x - or anything above/below value a for parameter y, etc.

Oh - as long as it's single supply, you're also welcome to suggest a *good* amp/s.

Thanks in advance,

Justin
