Chapter 1.  Product Overview

1.1

INTRODUCTION

This chapter provides an overview of the TC1047A Temperature-to-Voltage Converter 
PICtail™ Demo Board. and covers the following topics:
• What is the TC1047A Temperature-to-Voltage Converter PICtail™ Demo Board?
• What the TC1047A Temperature-to-Voltage Converter PICtail™ Demo Board Kit 

includes

1.2

WHAT IS THE TC1047A TEMPERATURE-TO-VOLTAGE CONVERTER 
PICTAIL™ DEMO BOARD?

The TC1047A Temperature-to-Voltage Converter PICtail™ Demo Board demonstrates 
how to interface the TC1047A to a PICmicro

®

 microcontroller using the PICkit™ 1 

Flash Starter Kit as a platform.  A PIC16F676 14-pin Flash-based 8-bit CMOS 
microcontoller device is included with the Demo Board that can be used with PICkit 1 
Flash Starter Kit, along with firmware that provides the interface to the TC1047A and 
the voltage-to-temperature conversion routines.
The TC1047A Temperature-to-Voltage Converter PICtail™ Demo Board can also be 
used as a “stand-alone” module to quickly add thermal sensing capablity to any existing 
application. This basic sensor functionality is implemented on a small Printed Circuit 
Board (PCB) and an interface via a standard 100 mil header.
