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.
