ADAU1962

12-Channel High Performance Differential Output, 192 kHz, 24-Bit DAC

Product Details

The ADAU1962 is a high performance, single chip, digital-to- analog converter (DAC) that provides 12 DACs with differential outputs using the Analog Devices, Inc., patented multibit sigma-delta (Σ-Δ) architecture. A SPI/I2C port is included, allowing a microcontroller to adjust volume and many other parameters. The ADAU1962 operates from 2.5 V digital and 3.3 V or 5 V analog supplies. A linear regulator is included to generate the digital supply voltage from the analog supply voltage.

The ADAU1962 is designed for low electromagnetic interference (EMI), evident in both the system and circuit design architectures. By using the on-board phase-locked loop (PLL) to derive the internal master clock from an external left-right frame clock (LRCLK)/frame clock, the ADAU1962 eliminates 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 of a smaller amplitude, further reducing emissions.

The ADAU1962 is available in an 80-lead LQFP package.

Product Details

The EVAL-ADAU1966Z and the EVAL-ADAU1962Z evaluation boards allow the user to evaluate the ADAU1962, 12 channel Digital to analog converter (DAC) or the ADAU1966, 16 channel DAC. The evaluation board will supply bit clock, LR clock and master clock and will except either 6 or 8 dual channel I2S data streams or multiple TDM (Time Division Multiplexed) data streams. The board has an S/PDIF receiver with RCA and optical connectors, as well as a discrete serial audio interface. Analog outputs are accessible via two db-25 connectors and channels 1 and 2 can be routed to an on-board headphone driver with the output on a stereo TRS Mini jack.

The EVAL-ADAU196x 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. The USBi is included with the evaluation board. 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 ADAU196x features, including high performance DAC operation.

Tried using this chip for a 5.1/Headphone USB DAC. This chip meets and exceeds all the performance criteria for even the highest fidelity audio DACs. Apart from the large amount of pins needed (a tqfp48 package would be nicer) i cant really see any problems with this part and would highly recommend it.
