OVERVIEW
The MCP3911 ADC Evaluation Board for 16-Bit MCUs system provides the opportunity
to evaluate the performance of the MCP3911 dual-channel ADC. It also provides a
development platform for 16-bit PIC
®
-based applications, using existing 100-pin PIC
microcontroller Plug-in Module (PIM) systems that are compatible with the Explorer 16
and other high pin count PIC
®
-based demo boards. The system comes with a
programmed PIC24FJ256GA110 PIM module that communicates with the Energy
Management Utility software for data exchange and ADC setup.

Feature Highlights
• Dual ADC MCP3911 output display using serial communication to the PC
software interface
• Simultaneous 55 ksps at OSR32 address loop ALL or 95 dB SINAD at OSR512
performance on MCP3911
• 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 MCP3911 devices; includes separate power
supplies and power planes on a 4-layer board.
• PICtail™ Plus connectors for Explorer 16 daughter board compatibility
