16-Channel, High Performance, 192 kHz, 24-Bit DAC
The ADAU1966A is designed for low EMI. This consideration is apparent in both the system and circuit design architectures. By using the on-board PLL to derive the internal master clock from an external left-right frame clock (LRCLK), the ADAU1966A can eliminate the need for a separate high frequency master clock and can be used with or without a bit clock. The DACs are designed using the latest Analog Devices continuous time architectures to further minimize EMI. By using 2.5 V digital supplies, power consumption is minimized, and the digital waveforms are a smaller amplitude, further reducing emissions.
Note that throughout this data sheet, multifunction pins, such as SCLK/SCL, are referred to by the entire pin name or by a single function of the pin, for example, SCLK, when only that function is relevant.

At least one model within this product family is in production and available for purchase. The product is appropriate for new designs but newer alternatives may exist.
The ADAU196xA can be controlled through either an I2C or SPI interface. A small external interface board EVAL-ADUSB2EBZ, also called USBi, connects to a PC USB port and provides either I2C or SPI access to the evaluation board through a ribbon cable. A graphical user interface (GUI) program, the Automated Register Window Builder, is provided for easy programming of the chip in a Microsoft® Windows® PC environment. The evaluation board allows demonstration and performance testing of most ADAU196xA features, including high performance DAC operation.
ADI has always placed the highest emphasis on delivering products that meet the maximum levels of quality and reliability. We achieve this by incorporating quality and reliability checks in every scope of product and process design, and in the manufacturing process as well. "Zero defects" for shipped products is always our goal.
