PURPOSE AND UTILITY OF THE MIXED SIGNAL PICtail? DEMO BOARD
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 REF s, Low Dropout Output (LDO) regulators and the PIC16F7X7 devices are
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.
CONTENTS OF THE MIXED SIGNAL PICtail DEMO BOARD KIT
This Mixed Signal PICtail? Demo Board includes:
