With such a small full range signal, applying large gain will not spread-out the signal range enough to sufficiently utilize the A/D range. The following is an example of how to remedy this situation.

Signal conditioning is an important aspect in almost all analog measurement applications such as blood pressure monitors, heart rate monitors, digital hearing aids, magnetic resonance imaging, ...

Sensor Platforms Inc. has introduced a sensor signal-conditioning IC that can work with multiple resistive, capacitive, inductive, voltage and pulsed sensor elements. The SSP1492 ...
