Evaluation board for AD1937Four 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 5 V and 3.3 V supplies for the AD1937/AD1939. The AD1937can be controlled through an SPI or I2 C interface. A small external interface board, EVAL-ADUSB2EBZ (also called USBi), connects to a PC USB port and provides I2C and 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 AD1937/AD1939 features, including four ADCs and eight DACs, as well as the digital audio ports.
