Overview

The TLV320AIC3254 is a low-power stereo audio codec featuring integrated miniDSP engines for advanced digital signal processing. It supports high-resolution 32-bit audio and provides flexible analog and digital I/O, including stereo headphone and line outputs, making it suitable for portable audio applications.

Why Choose This Part

The inclusion of dual miniDSP cores allows for complex audio processing like multiband EQ and dynamic range compression without high CPU overhead. Its PowerTune technology enables engineers to optimize power consumption based on performance requirements, scaling from ultra-low power to high-performance modes.

Applications

Wireless Headsets
Utilize integrated miniDSP for echo cancellation and noise suppression in compact, battery-powered designs.
Portable Media Players
Take advantage of high SNR DACs and PowerTune technology to extend battery life while maintaining audio quality.
Digital Voice Recorders
Support for stereo digital and analog microphones with integrated low-noise PGAs for high-quality voice capture.
Mobile Communications
Hardware-based signal processing offloads the host processor for filtering and equalization tasks.
