Analog DevicesEVAL-AD1938AZ

Evaluating the AD1938 Four ADC/Eight DAC with PLL 192 kHz, 24-Bit Codec.  The evaluation board must be connected to an external ±12 V dc power supply and ground. On-board regulators derive 3.3 V supplies for the AD1938. The AD1938 is controlled through an SPI interface. A small external interface board, EVAL-ADUSB2EBZ (also called USBi), connects to a PC USB port and provides SPI access to the evaluation board through a ribbon cable. A graphical user interface (GUI) program is provided for easy programming of the chip in a Microsoft® Windows® PC environment. The evaluation board allows demonstration and performance testing of most AD1938 features, including four ADCs and eight DACs, as well as the digital audio ports.
