Analog Devices EVAL-AD7688SDZ Evaluation Board is designed as a fully featured evaluation kit for the AD7688 500kSPS Differential PulSAR® Analog-to-Digital Converter (ADC) housed in a 10-lead µSOIC or 10-lead QFN chip scale package.
The AD7688 features a very low power high-speed 16-bit sampling ADC with no missing codes, an internal conversion clock, and a versatile serial interface port operates from a single 5V power supply. The EVAL-AD7688SDZ Evaluation Board operates in standalone mode or in conjunction with the System Development Platform, EVAL-SDP-CB1Z.
When operated with the System Development Platform software, EVAL-AD7688SDZ enables the designer to perform detailed analysis of the AD7688's performance.
