ADS8688EVM Features
• Hardware and software required for diagnostic testing as well as accurate performance evaluation of the
ADS8688 ADC
• USB powered—no external power supply is required
• The PHI controller that provides a convenient communication interface to the ADS8688 ADC over USB 2.0
(or higher) for power delivery as well as digital input and output
• Easy-to-use evaluation software for 64-bit Microsoft Windows™7, Windows 8, and Windows 10 operating
systems
• The software suite includes graphical tools for data capture, histogram analysis, and spectral analysis. This
suite also has a provision for exporting data to a text file for post-processing. Fig
• Integrated 4.096-V voltage reference.
• Bipolar (±10.24 V, ±5,12 V, ±2.56 V ) or unipolar (0 V to 10.24 V, 0 V to 5.12 V) input ranges for each channel.
• Onboard, second-order, Butterworth, low-pass filters for four channels.
• Onboard regulator for generating a ±15-V bipolar supply for second-order, Butterworth, low-pass filters.
• Capable of accepting a ±100-mV signal on the negative analog inputs (AIN_xGND).
