The OPA140A operational amplifier is a low-power JFET input amplifier that features good drift and low input bias current. The rail-to-rail output swing and input range that includes V— allow designers to take advantage of the low-noise characteristics of JFET amplifiers while also interfacing to modern, single-supply, precision analog-to-digital converters (ADCs) and digital …
OPA140 or AD4625 for the servo? 1/5 or less the noise of ...
https://www.diyaudio.com/community/threads/opa140-or-ad4625-for-the-servo-1-5-or-less-the-noise-of-ad820.319471/
Just to be clear, the OPA140 is not a 'shoddy' JFET amplifier - it performs extremely well for a non chopper stabilized amplifier. However, the voltage offset is ~20x higher than the ADA4522, and it will exhibit 2x the noise in the 0.1-10Hz band, a region where a DC servo circuit will have significant gain.
OPA140: There are two different OPA140 tina simulation ...

Note however, that there is a setup problem with your circuit. The OPA140 is powered by a single +5 V supply, and the common mode voltage is +2.5 V. See from the OPA140 datasheet Electrical Characteristics table that the Common-mode voltage (VCM) range is (V–) – 0.1 to (V+) – 3.5 V, for TA = –40°C to 125°C.
