4 ADC With PLL, 192 KHz, 24-Bit Codec

The AD1974 is a high performance, single-chip codec that pro-vides four Analog-to-digital converters (ADCs) with differential inputs using the Analog Devices, Inc. patented multibit sigma-delta (-) architecture. An SPI port is included, allowing a Microcontroller to adjust volume and many other parameters. The AD1974 operates from 3.3 V digital and Analog supplies. The AD1974 is available in a single-ended output 48-lead LQFP.
The AD1974 is designed for low EMI This consideration is apparent in both the system and circuit design architectures. By using the on-board phase-locked loop (PLL) to derive the master Clock from the LR Clock or from an external crystal, the AD1974 eliminates the need for a separate high frequency master Clock and CAN also be used with a suppressed bit Clock The ADCs are designed using the latest continuous time architectures from Analog Devices to further minimize EMI By using 3.3 V supplies, power consumption is minimized, further reducing emissions.
