AN-1106 Custom Instrumentation Amplifier Design
This application note describes some of the fine points of designing an instrumentation amplifier with op-amps. We will cover how to maintain good common-mode rejection and output signal linearity. In addition, we will explain various filters that can be integrated in the design to provide additional performance improvements. For our example, we use Silego’s SLG88102V ultra-low power, quad op-amp integrated circuit.
