ADAU1966:  16-Channel 118dB SNR Differential Output, 192 kHz, 24-Bit DAC

Product Details

Product Status:Recommended for New Designs

The ADAU1966 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, 3.3V or 5V IOVDD and 5V analog supplies. A linear regulator is included to generate the digital supply voltage from the analog supply voltage. The ADAU1966 is available in an 80-lead LQFP package.

The ADAU1966 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 master clock from an external LR (Frame) clock, MCLK, or from an external crystal, the ADAU1966 can eliminate the need for a separate high frequency master clock and can also be used with a 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.
