Nuvoton Technology Corp., a provider of consumer-electronics and computer ICs, introduced the NAU88L25, a new ultra low power audio codec device optimized for audio headphone and headset applications. The newest member of Nuvoton’s flagship emPowerAudio family, the NAU88L25 delivers exceptional audio performance at battery-friendly power levels: 124dBA stereo digital-to-analog converter (DAC) signal-to-noise (SNR), and 101dBA stereo analog-to-digital converter (ADC) SNR.
The NAU88L25 supports advanced audio accessory detection including audio jack insertion / ejection, up-to 8 button detection with short / long press support, microphone and ground pin detection with auto internal switching, which will simplify the challenges of detecting different audio headsets and accessory types with no additional components and reducing click/pop noise during the detection process.
The new audio CODEC incorporates a 24-bit signal processing engine including programmable biquad filters and DRC (Dynamic Range Compressor), which can maximize audio quality and suppress any undesirable frequency components. With its ultra-low power consumption in all key areas, highly flexible and configurable accessory detection, and reference audio CODEC driver for Linux, Android, and Windows OS, the NAU88L25 simplifies designers’ efforts and gets their products to market quickly.
Nuvoton, a former subsidiary of Winbond Electronics Corp., has shipped more than one-billion voice and audio chips in the last twenty-plus years. The emPowerAudio line was developed to help designers worldwide to successfully develop high-fidelity audio applications, at price points that will fuel growth in high-quality audio in an every-broadening range of portable devices.
“Consumers these days are willing to spend more time listening to music through high quality audio headphones and headsets,” said Mike Luh, marketing director of audio product business group at Nuvoton Technology Corporation America. “The NAU88L25 is designed to address today’s high expectation for clear and better audio / sound quality and to enhance the overall user experience by allowing more sophisticated accessory controls.”
