FET Op Amp

Posted on March 3, 2010 by Rust

THE FM3954 monolithic-dual gives us an ideal low-offset and acts as low-drift buffer function for the LM101A op amp. Track over it’s bias current range thus improving common mode rejection is the excellent matching characteristics of the FM3954.

Here’s the circuit diagram:
