Working Principle

The ADAU1381BCBZ-RL consists of an audio processor and an onboard circuit that can control and route the audio signals. It uses a digital signal processor (DSP) to process incoming audio signals. Once the audio signals have been processed, the digital signal processor then passes the output signals to the output channels. The audio processor also provides an output simulator, which is used to monitor and control audio signals across the various channels.

The chip supports a flexible mode of operation. It can be used in standalone mode or can be integrated into a system using its serial audio bus. Its serial audio bus supports various audio formats such as PCM, AC-3 and MP3. This makes it well suited for applications such as mobile phones, media players and portable music players.

The ADAU1381BCBZ-RL also features a digital-to-analog converter (DAC). This allows it to convert digital audio signals into analog signals. This makes it suitable for use in audio equipment such as digital audio players, external speakers and headphones.

The ADAU1381BCBZ-RL also supports various audio effects, including reverb, chorus, delay, EQ and crossfade. It also has a built-in microphone preamplifier with support for various microphone types, including electret and dynamic microphones.

Overall, the ADAU1381BCBZ-RL is well suited for applications such as digital audio playback, audio streaming, audio encoding, voice recognition, speech recognition, and noise cancellation. Its integrated audio processor and low power, fixed-point audio DSP make it ideal for integration into audio products such as media players, set-top boxes, mobile phones, portable music players, and other consumer electronics.
