PRODUCT OVERVIEW

The AD1836A is a high performance, single-chip codec that

provides three stereo DACs and two stereo ADCs using ADI’s

patented multibit Σ-∆ architecture. An SPI® port is included,

allowing a microcontroller to adjust volume and many other

parameters. The AD1836A operates from a 5 V supply, with

provision for a separate output supply to interface with low

voltage external circuitry. The AD1836A is available in a 52-lead

MQFP (PQFP) package.
