Kit Overview

The Analog Devices EVAL-ADAU1966ZEVAL-ADAU1966Z Evaluation Board is used for evaluating the ADAU1966ADAU1966 High Performance Low Power Multibit Sigma-Delta DAC. The evaluation board must be connected to an external 12 V dc power supply and ground; the board draws approximately 150 mA. On-board regulators derive 9 V, 5 V, and 3.3 V supplies for the ADAU1966 and peripherals. The ADAU1966 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 ADAU1966ADAU1966 features, including high performance digital-to-analog converter (DAC) operation.

The board has an S/PDIF receiver with RCA and optical connectors, as well as a discrete serial audio interface that is available on the Analog Devices, Inc. system development platform (SDP) interface. Analog outputs are accessible with two D-sub, 25-pin connectors using the professional audio standard. A single D-sub, 25-pin to XLR male cable is included with the board for connecting individual DAC channels to an audio system.

The ADAU1966ADAU1966 is a high performance, single-chip DAC that provides sixteen digital-to-analog converters (DACs) with differential output using the Analog Devices, Inc. patented multi-bit sigma-delta (Σ-Δ) architecture. An SPI/I2C port is included, allowing a microcontroller to adjust volume and many other parameters. The ADAU1966 operates from 2.5 V digital and 3.3V or 5V analog supplies. A linear regulator is included to generate the digital supply voltage from the analog supply voltage.

Key Applications: Automotive audio systems, Home Theater Systems, Digital audio effects processors
