Hi,
I'm trying to connect the ADA8691 amplifier with ADMP411 microphone, but I can't find the input resistance of the amplifier. Thanks,

Hi hulala,
Because the AD8691 is a CMOS amplifier, it should have very high input impedance. I do not think there will be any problems with interfacing this to the ADMP411. I have communicated with the engineer of this part to try and see whether I can provide you a typical value of its input impedance. I'll get back to you on this.
Thanks!
Kris
