Description

The Electronic Component Model AD1836AASZ is a high-performance single-chip codec that provides three stereo DACs and two stereo ADCs. It utilizes Analog Devices, Inc.'s patented multibit Σ-Δ architecture and operates from a 5V supply. With the inclusion of an SPI® port, it allows a microcontroller to adjust volume and other parameters. This model is available in a 52-lead MQFP (PQFP) package, making it suitable for use in various applications.
