AD1938 Datasheet PDF - ADI

●GENERAL DESCRIPTION

●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. An SPI® or I2C® port is included, allowing a microcontroller to adjust volume and many other parameters. 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.
