Part of a project I'm working on i need to build a traditional 3 op amp instrumentation amplifier with dc offset adjustment and low frequency CMRR adjustment.
The questions i have would be what Opamp would be best suited for this? i appreciate there are ready made instrumentation amps but i need to use a 3 op amp version.
To adjust the dc off set is it as simple as connecting a pot to the last op amps offset null connections?
and lastly how does one adjust the CMRR?
