The circuit diagram of high precision and low offset current follower (LM11C, LF351)

Published:2011/8/8 22:11:00 Author:Felicity | Keyword: high precision, low offset, current follower | From:SeekIC

LM11C has a very low offset current (around 100pA), a low misalignment voltage( around 0.6 mV) and a 110dB CMRR.LF351 operational amplifier has a misalignment voltage about 10mv ,a static current around 3.4mA and a input offset current about 200PA. In this circuit, A2 adopts alternating-current coupling to reduce offset current. And this circuit has a long overload recovery time and the common-mode input voltage cannot exceed ±l0V.
