1.1

INTRODUCTION

This chapter provides an overview of the MCP355X Tiny Application Sensor Demo 
Board and covers the following topics:
• What is the MCP355X Tiny Application Sensor Demo Board?
• What the MCP355X Tiny Application Sensor Demo Board kit includes

1.2

WHAT IS THE MCP355X TINY APPLICATION SENSOR DEMO BOARD?

The  MCP3550/1/3 devices are 2.7V to 5.5V low-power, 22-bit Delta-Sigma 
Analog-to-Digital Converters 

(

ADCs).  The MCP355X Tiny Application Sensor Demo 

Board is used to demonstrate the most basic application of the devices using a 
ratiometric connection with V

DD

 as V
