MCP3901 ADC EVALUATION BOARD
FOR 16-BIT MCUs USER’S GUIDE
 2010 Microchip Technology Inc. DS51845B-page 9
Chapter 1. Hardware Description
1.1 OVERVIEW
The MCP3901 ADC Evaluation Board for 16-Bit MCUs system provides the ability to
evaluate the performance of the MCP3901 dual channel ADC. It also provides a
development platform for 16-bit PIC
®
MCU-based applications, using existing 100-pin
Plug-in Module (PIM) systems compatible with the Explorer 16 and other high pin count
PIC MCU demo boards. The system comes with programmed dsPIC33FJ256GP710
PIM modules that communicate with the LabVIEW™ software GUI for data exchange
and ADC setup.
1.1.1 Feature Highlights
• Dual ADC MCP3901 output display using serial communication to PC software
interface
• Simultaneous 4 ksps at 90 dB SINAD and top speed of 55 ksps performance on
dual MCP3901 channels
• System and ADC performance analysis through graphical PC tools showing noise
histogram, frequency domain (FFT), time domain scope plot, and statistical
numerical analysis
• Robust hardware design with analog grounding and analog/digital separation,
allowing low noise evaluation of MCP3901 devices. Separate power supplies and
power planes – 4 layer board
• PICtail™ Plus connectors for Explorer 16 daughter board compatibility
