Overview
The AD1836AASZ, produced by Analog Devices Inc., is a high-performance, single-chip codec designed for multichannel audio applications. It features three stereo Digital-to-Analog Converters (DACs) and two stereo Analog-to-Digital Converters (ADCs) utilizing Analog Devices' patented multibit Σ-Δ architecture. This codec operates from a 5 V supply and includes provisions for a separate output supply to interface with low-voltage external circuitry. The AD1836AASZ is packaged in a 52-lead MQFP (PQFP) and includes an SPI port for microcontroller control, enabling adjustments to volume and other parameters.
