Application note

Plethysmograph based on the TS507

Introduction
This application note provides a method to make an analog front-end plethysmograph (from
the ancient greek plethysmos, which means increase), which is an instrument for measuring
changes in volume within an organ or whole body, usually resulting from fluctuations in the
amount of blood or air it contains. In this context, we refer in particular to the fluctuations in
the quantity of blood in blood vessels.
