GENERAL DESCRIPTION
The AD1836 is a high-performance, single-chip codec providing three stereo DACs and two stereo ADCs using ADI’s patented multibit sigma-delta architecture. An SPI port is included, allowing a microcontroller to adjust volume and many other parameters. The AD1836 operates from a 5 V supply, with provision for a separate output supply to interface with low-voltage external circuitry. The AD1836 is available in a 52-lead MQFP (PQFP) package.
