ANALOG DEVICES AD1938WBSTZ

AD1938 is a high performance, single-chip codec that provides four analogue-to-digital converters (ADCs) with differential input and eight digital-to-analogue converters (DACs) with single-ended 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. It is designed for low EMI. This consideration is apparent in both the system and circuit design architectures. By using the on-board PLL to derive the host clock from the LR clock or from an external crystal, it eliminates the need for a separate high frequency host clock and can also be used with a suppressed bit clock. The DACs and ADCs are designed using the latest Analog Devices continuous time architectures to further minimize EMI. It is used in applications such as automotive audio systems, home theatre systems, set-top boxes, digital audio effects processors.
