AD1937 - Analog Devices

AD1937 (AD1935 - AD1939) 4 ADC/8 DAC

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 .
