INTRODUCTION
FEATURES
GETTING STARTED
Chapter 2. Installation and Operation
The Mixed Signal PICtail™ Demo Board demonstrates several Microchip analog
products in a signal chain configuration. The product families demonstrated include
DACs, ADCs, V
precision analog products for specific applications can be challenging due to noise
sources related to the PCB layout and not the silicon under evaluation. The Mixed Signal
PICtail™ Demo Board provides the necessary hardware and firmware to exercise each
of these devices in real-world applications. Users can quickly modify the existing
hardware and firmware to validate functionality for their specific system needs.
The Mixed Signal PICtail™ Demo Board has the following features:
• Printed Circuit Board (PCB) is a 4-layer board designed to minimize external
• A 28-pin PICmicro (PIC16F767) microcontroller footprint is provided to permit
• The 14-pin header is designed to seamlessly interface to the PICkit™ 1 Flash
• Firmware demonstrating DTMF generation on the MCP492X/482X DAC is
• Firmware demonstrating a precision sine-wave generation on the TC132X DAC is
• Firmware to configure and read the MCP330X/320X SAR ADCs is included
• Two precision voltage references (V
• Flexible amplifier circuit layout supports a dual op amp in multiple configurations
• Four DIP switches allow simple firmware mode selection are supported
• Two indicator LEDs (red and green) are supported
• Can be powered by either the PICkit™ 1 Flash Starter Kit or by an external 9V
The Mixed Signal PICtail™ Demo Board is assembled and tested for evaluation and
demonstration of the MCP492X, MCP482X, TC132X, MCP3551, MCP3302,
MCP3204, MCP1541, MCP1701, PIC16F767 and MCP617 features. Additional
product samples with footprints supported by this board are included. A block diagram
of the demo board is shown in Figure 2-1. Refer to Appendix A. “Schematics and
Layouts” and Appendix B. “Bill-Of-Materials (BOM)” for more detailed circuit
information.
