Analog Devices AD1935

The AD193X family are high performance, single-chip codecs that provide 4 ADCs with differential input and 8 DACs with either single-ended or differential output using ADI’s patented multibit sigma-delta architecture. The AD193X family operates from 3.3V digital and analog supplies. The AD193X is available in a 48-lead (SE output) or 64-lead (differential output) LQFP package.

GENERAL DESCRIPTION

An SPI® or I2C® port is included, allowing a microcontroller to adjust volume and many other parameters. The AD193X 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 master clock from L-R clock, the AD193X eliminates the need for a separate high frequency master clock.
