Overview

The TLV320AIC3204 (also known as the AIC3204) is a flexible, low-power stereo audio codec featuring programmable PowerTune technology for optimizing power consumption versus performance. It integrates a stereo ADC and DAC supporting sample rates up to 192kHz, alongside a highly configurable analog front-end and digital signal processing blocks.

Why Choose This Part

This codec stands out for its PowerTune technology, allowing engineers to trade off SNR for ultra-low power consumption (as low as 4.1mW for stereo DAC playback). It provides extensive analog routing flexibility with six single-ended or three fully-differential inputs and includes an integrated LDO to simplify power rail design.

Applications

Portable Audio Players
Utilizes the 4.1mW low-power playback mode and integrated headphone amplifiers for extended battery life.
Voice-over-IP (VoIP) Endpoints
Employs the integrated AGC and noise-filtering digital effects to improve voice clarity in communication headsets.
Wireless Audio Accessories
Compact 5x5mm VQFN footprint and digital microphone support make it ideal for Bluetooth speakers and earbuds.
Industrial Voice Recognition
Uses the low-noise PGA and differential analog inputs to interface with sensitive transducers in noisy environments.
