ADAU1382BCPZ

Overview

The ADAU1382BCPZ is a low-power, 24-bit stereo audio codec manufactured by Analog Devices Inc. It integrates a configurable sound engine for record and playback processing, including wind noise filtering, automatic level control, and a 5-band equalizer with notch filter capabilities. The device supports sampling rates from 8 kHz to 96 kHz and features a built-in 400 mW speaker amplifier into an 8 Ω load. Input options include stereo pseudo-differential or single-ended analog microphone inputs, optional stereo digital PDM microphone inputs, and a dedicated analog beep input. Output paths consist of a stereo line output and the integrated speaker driver. Control is managed via I²C or SPI protocols, while serial audio data supports I2S, left-justified, right-justified, or TDM modes.

Feature Summary

• Integrated sound engine providing advanced audio processing such as wind noise filtering, automatic level control, and multi-band equalization.
• Built-in high-efficiency speaker amplifier capable of driving dynamic speakers directly without external components.
• Flexible input architecture supporting both analog pseudo-differential/single-ended microphones and digital pulse-density modulation (PDM) microphones.
• Configurable serial audio interface compatible with standard protocols like I2S, left-justified, right-justified, and TDM.

Applications

• Digital still cameras
• Digital video cameras
