High Speed Instrumentation Amplifier

For applications requiring higher CMRR the composite circuit of Figure 43 uses the two amplifiers of the CLC412

to create balanced inputs for the CLC420 voltage-feedback op amp. The DC CMRR can be fine tuned through

an RC network between the outputs (A and B) of the two amplifiers of the CLC412.

Figure 43.

Non-Inverting Current-Feedback Integrator

The circuit of Figure 44 achieves its high speed integration by placing one of the CLC412's amplifiers in the

feedback loop of the second amplifier configured as shown.
