INTRODUCTION
PURPOSE AND UTILITY OF THE MIXED SIGNAL PICtail™ DEMO BOARD
CONTENTS OF THE MIXED SIGNAL PICtail DEMO BOARD KIT
This chapter provides an overview of the Mixed Signal PICtail™ Demo Board and
covers the following topics:.
• Purpose and utility of the Mixed Signal PICtail™ Demo Board
• Contents of the Mixed Signal PICtail™ Demo Board Kit
The Mixed Signal PICtail™ Demo Board allows the system designer to quickly evaluate
the suitability of several Microchip analog products for their product’s design.
Microchip’s Digital-to-Analog Converters (DACs), Analog-to-Digital Converters
(ADCs), V
supported. Evaluating precision analog products for specific applications can be
challenging for practical reasons. First, many products are only available in
surface-mount packages. Secondly, analog circuits tend to be affected adversely by
system noise. Common breadboarding techniques are not practical for these reasons.
The Mixed Signal PICtail™ Demo Board utilizes a 4-layer Printed Circuit Board (PCB),
with attention paid to reducing system noise.
The Mixed Signal PICtail™ Demo Board can isolate a specific device’s performance to
establish baseline performance. The board can be customized quickly for specific
system requirements.
This Mixed Signal PICtail™ Demo Board includes:
• The Mixed Signal PICtail™ Demo Board PCB
• PIC16F767 firmware that demonstrates how to configure and write to the
• PIC16F767 firmware demonstrating DTMF generation using a DAC
• PIC16F767 firmware demonstrating sine-wave generation using a DAC
• PIC16F767 firmware to configure and read the MCP330X/320X SAR ADCs
• PIC16F767 firmware that configures and reads the MCP3551 Sigma-Delta ADC
• MCP617 dual op amp (standard 8-pin dual layout) that can be configured as an
• Four DIP switches allow simple firmware mode selection
• Two indicator LEDs (red and green) for visual feedback
• PICkit™ 1 Flash Starter Kit’s 14-pin header provides an interface to Microchip’s
MCP492X, MCP482X and TC132X DAC products
