OVERVIEW
The MCP3903 ADC Evaluation Board for 16-Bit MCUs system lets users evaluate the
performance of the MCP3903 six-channel ADC. It also provides a development
platform for 16-bit PIC
®
MCU-based applications, using existing 100-pin PIM systems,
compatible with the Explorer-16 and other high pincount PIC demo boards. The system
comes with programmed PIC24FJ128GA010 PIM modules that communicate with the
LabView GUI for data exchange and ADC setup.

Feature Highlights
• Six-channel ADC MCP3903 output display using serial communication to the
PC Software Interface and LCD
• Simultaneous 4 ksps at 91 dB Signal-to-Noise and Distortion Ratio (SINAD)
performance. The ADC can run up to 64 ksps.
• System and ADC performance analysis through graphical PC tools showing Time
domain scope plot, Frequency Domain (FFT), and statistical numerical analysis.
• Robust hardware design with analog grounding and analog/digital separation,
allowing low noise evaluation of the MCP3903 devices. Separate power supplies
and power planes - 4 layer board.
• Pigtail Plus connectors for Explorer-16 daughter board compatibility.
