Default ad8641/8642/8643 for preamp ?

Hi,

As a newbie, I need help for verifying a op amp datasheet.

I need +/-9v low current <0,3ma op amps for (single ended) 0/+18db first stage 5M impedance, a piezo charge mode amplifier, and a buffer. PSU with true ground on it own layer.

Does the ad86x serie (soic only) is ok, compared to a lt135x, or tle206x ?

I've chosen the ad864x based on it low bias input to try to limit the noise of stages loaded with 5M, and on it lower distortion compared to tle206x. Lt135x, bjt op amp, has lower impedance, lower noise and distortion and should be the better choice for the buffer ?

Other suggestion ?

I suppose it would be easy to answer for someone with better audio electronic knowledge...

Thanks for help !

Damien
