ADAU1966AWBSTZ

ADAU1966A is a high-performance, single-chip digital-to-analog converter (DAC) that provides 16 DACs with differential or single-ended outputs using the Analog Devices, Inc., patented multibit sigma-delta (Σ-Δ) architecture. A serial peripheral interface (SPI)/I2C port is included, allowing a microcontroller to adjust volume and many other parameters. It operates from 2.5V digital and 3.3V analogue supplies. A linear regulator is included to generate the digital supply voltage from the analogue supply voltage. he 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 host clock from an external left-right frame clock (LRCLK), the ADAU1966A can eliminate the need for a separate high frequency host clock and can be used with or without a bit clock. Typical applications include automotive audio systems, home theatre systems and digital audio effects processors.
