Part Details:

2 ADC/8 DAC with PLL, 192 kHz, 24-Bit Codec AD1928 FEATURES GENERAL DESCRIPTION PLL-generated or direct master clock The AD1928 is a high performance, single-chip codec that Low EMI design provides two analog-to-digital converters (ADCs) with differ- 108 dB DAC/107 dB ADC dynamic range and SNR ential input and eight digital-to-analog converters (DACs) with -94 dB THD + N single-ended output using the Analog Devices, Inc., patented 3.3 V single supply multibit sigma-delta (-) architecture. An SPI port is included, Tolerance for 5 V logic inputs allowing a microcontroller to adjust volume and many other Supports 24 bits and 8 kHz to 192 kHz sample rates parameters. The AD1928 operates from 3.3 V digital and analog Differential ADC input supplies. The AD1928 is available in a 48-lead (single-ended Single-ended DAC output output) LQFP package. Other members of this family include a Log volume control with autoramp function differential DAC output and I2C® control port versions. SPI® controllable for flexibility The AD1928 is designed for low EMI. This consideration is Software-controllable clickless mute apparent in both the system and circuit design architectures. Software power-down By using the on-board PLL to derive the master clock from the Right-justified, left-justified, I2S-justified, and TDM modes LR clock or from an external crystal, the AD1928 eliminates the Master and slave modes up to 16-channel input/output need for a separate high frequency master clock and can be 48-lead LQFP used with a suppressed bit clock. The digital-to-analog and APPLICATIONS analog-to-digital converters are designed using the latest Automotive audio systems Analog Devices continuous time architectures to further Home theater systems minimize EMI. By using 3.3 V supplies, power consumption is Set-top boxes minimized, further reducing emissions.
