AD1939

4 ADC / DAC 8与PLL ， 192千赫， 24位编解码器 4 ADC/8 DAC with PLL, 192 kHz, 24 Bit CODEC

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 ’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.
