EVAL-AD5592R-PMDZ Overview

EVAL-AD5592R-PMDZ is a minimalist 8-channel, 12-Bit, Configurable ADC/DAC/GPIO with on-chip Reference, SPI interface PMOD module. This boards serve as low-cost alternatives to the full-featured product evaluation boards, with terminal block connections and no extra signal conditioning.

This user guide will focus on the hardware aspect of the EVAL-AD5592R-PMDZ including the connectors, indicators, and different configurations a user would require in order to use the hardware. There are also link to the design files as well as software reference designs that use the hardware with example embedded firmware for a real demo.

Test Points

User can also check the SPI signal quality, supply and reference voltage of the board using test points labeld SS, MOSI, MISO, VLOGIC and VREF


Voltage reference configuration

The default connection of AD5592R Vref pin is shorted at pin 1 of JP1 solder jumper where you can easily configure your voltage reference input at pin 1 of terminal block P2, either from external source or internal 2.5V

LED Indicator

The DS1 is the power green LED indicator of the board.
