TLV320AIC3256IRSBR Stereo Audio Interface 32 b I²C, Serial, SPI™
The TLV320AIC3256IRSBR is a high-performance, ultra-low power stereo audio codec from Texas Instruments, designed for portable audio, voice recognition, and professional recording applications. This advanced IC integrates 24-bit stereo ADC and DAC with programmable sample rates up to 192kHz, delivering 114dB SNR for playback and 108dB SNR for recording to ensure studio-grade audio quality. Featuring five fully programmable digital signal processors (MiniDSP cores), the device supports real-time audio effects processing, including equalization, dynamic range control, and 3D sound enhancement, making it ideal for smart speakers, USB headsets, and automotive infotainment systems. The codec operates on an extremely low 1.8V digital core voltage with programmable power stages that optimize consumption down to 3mW in voice mode, enabling extended battery life in wireless applications.
Texas Instruments provides complete development support including the PurePath Studio™ graphical configuration tool, pre-tuned audio algorithms, and evaluation modules to accelerate product development. The codec's hardware-based register protection prevents accidental configuration changes, while its seamless mode transitions eliminate audio artifacts during power state changes. These features make the TLV320AIC3256IRSBR particularly suitable for AI voice assistants, hearing aids, and multi-channel recording equipment where audio fidelity and power efficiency are paramount.
