PRODUCT OVERVIEW
The AD1836A is a high performance, single-chip codec that provides three stereo DACs and two stereo ADCs using Analog Devices, Inc., patented multibit Σ-Δ 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.
