Chapter 2. Installation and Operation
The MCP355X Tiny Application Sensor Demo Board is designed to demonstrate the
performance of the MCP3550/1/3 devices in a simple low-cost application. The circuit
uses a ratiometric sensor configuration and uses the system power supply as the
voltage reference. The extreme common mode rejection capability of the MCP3551
device, along with it’s excellent normal mode power supply rejection at 50 and 60 Hz,
allows for this system performance. The functional circuit block diagram is shown in
Figure 2-1.
