Description

The AD1836AAS is a high-performance, single-chip codec that belongs to the Interface - CODECs product category. It utilizes ADI’s patented multibit Σ-∆ architecture to provide three stereo DACs (Digital-to-Analog Converters) and two stereo ADCs (Analog-to-Digital Converters). This codec operates from a 5 V supply and supports 16-/18-/20-/24-bit data. It also supports a 24-bit and 96 kHz sample rate for high-quality audio processing. The AD1836AAS features multibit Σ-∆ modulators with data directed scrambling, ensuring optimal performance. The differential output further enhances its overall audio quality. It comes in a 52-lead MQFP (PQFP) package.
