This document introduces the design and setup of the evaluation board for the AD1974 Four ADC with PLL 192 kHz, 24-Bit Codec, including connecting external power supply, AD1974 control interface, functional block diagram, MCLK routing, power supply, etc.
This document provides instructions for the AD1974 evaluation board, covering package contents, functional block diagrams, and setup procedures. The board requires an external ±12 V dc power supply and allows the AD1974 to be controlled via an SPI interface connected to a PC through a USBi control interface board.
The board requires a power supply input of ±12 V dc and ground connected to the three binding posts.
The +12 V input draws approximately 250 mA.
The passive crystal runs the AD1974 at 12.288 MHz.
