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.
