The EVAL-AD7714-5EB from Analog Devices is an evaluation board designed for the AD7714-5, a 24-bit sigma-delta Analog-to-Digital Converter (ADC). This board is intended for low-frequency applications and provides a complete analog front-end. It can accommodate either three fully-differential or five pseudo-differential input channels, directly accepting low-level signals from transducers and outputting a serial digital word.
The evaluation board operates from a single +5V supply for AVDD, which also powers the AD780 reference. The DVDD can be operated at either +5V or +3V. For single supply operation, AVDD and DVDD can be connected together. The board includes an AD780 ultra-high precision bandgap reference, a 2.4576MHz crystal, and digital buffers for interfacing.
Connectivity options include a 9-way D-type connector and a 36-way Centronics connector, allowing for direct hook-up to a PC's printer port. PC software is available for control and data analysis. The board features various linking options for flexible configuration. Both AGND and DGND planes are provided and connected at the AD7714, with recommendations to avoid ground loops. Decoupling capacitors are included for both supplies.
