AD1939WBSTZ-RL

4 ADC/8 DAC with PLL,  192 kHz, 24-Bit Codec

GENERAL DESCRIPTION  

The AD1939WBSTZ AD1939 is a high performance, single-chip codec that  provides four analog-to-digital converters (ADCs) with  differential input, and eight digital-to-analog converters (DACs)  with differential output using the Analog Devices, Inc. patented  multibit sigma-delta (Σ-Δ) architecture. An SPI port is included,  allowing a microcontroller to adjust volume and many other  parameters. The AD1939WBSTZ AD1939 operates from 3.3 V digital and analog  supplies. The AD1939WBSTZ AD1939 is available in a 64-lead (differential  output) LQFP package.
