AK7811ABB

Overview

The AK7811ABB is a high-performance, low-power stereo audio CODEC manufactured by Asahi Kasei Microdevices. It integrates two differential microphone inputs and two line-level outputs with integrated Class-D speaker drivers. The device supports 24-bit audio resolution at sampling rates up to 96 kHz. Key electrical specifications include a signal-to-noise ratio of 103 dB for playback and 95 dB for recording. It operates from a single 3.3 V supply and features an I2S interface for digital audio connectivity.

Feature Summary

Integrated Class-D amplifier output for direct speaker driving without external power stages
High-fidelity analog front-end supporting differential microphone inputs and line outputs
Low-power architecture optimized for portable battery-operated devices
Digital interface compatibility with standard I2S protocols for system integration

Applications

Smartphones and mobile communication devices
Portable media players and MP3 players
Tablet computers and handheld gaming consoles
Voice recognition modules and smart speakers

Procurement Notes

Verify the specific suffix 'ABB' against the manufacturer's current datasheet to confirm pinout and package configuration. Ensure the source document matches the exact part number to avoid confusion with similar AK series variants. Check for RoHS compliance status in the official ordering information section.

Selection Notes

Select this component when a compact solution combining ADC, DAC, and Class-D amplification is required. It is suitable for designs prioritizing board space reduction and power efficiency. Compare total harmonic distortion specifications against application requirements for audio quality standards.

Part Context

This model belongs to the AK78xx series of audio CODECs designed for consumer electronics. The series emphasizes integration to reduce external component count. It serves as a bridge between digital baseband processors and analog audio transducers in modern multimedia systems.

Replacement Considerations

Consult the manufacturer's cross-reference guide for verified substitutes. Direct replacements must match the pinout and functional block diagram. Verify thermal performance and supply voltage compatibility before substitution.
