Overview
The AD1836ACSZ, produced by Analog Devices Inc., is a high-performance, single-chip codec designed for multichannel audio applications. It integrates three stereo Digital-to-Analog Converters (DACs) and two stereo Analog-to-Digital Converters (ADCs) using 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 AD1836ACSZ is available in a 52-lead MQFP (PQFP) package and features an SPI port for microcontroller control, enabling adjustments to volume and other parameters.
