Audio Interface NAU88C22YG TR Features
The NAU88C22YG TR boasts a wide range of features that enhance its versatility and performance. It includes integrated drivers for speakers, headphones, and differential or stereo line outputs, along with a pre-amplifier for stereo differential microphones, significantly reducing the need for external components. The fractional PLL (Phase-Locked Loop) allows the codec to generate any audio sampling rate from 8kHz to 192kHz using any system clock between 8MHz and 33MHz. Advanced on-chip digital signal processing includes a 5-band equalizer, a 3-D audio enhancer, a mixed-signal automatic level control for microphones, and a digital limiter/dynamic range compressor for playback paths. Additional digital filtering options in the ADC path simplify the implementation of specific application requirements such as wind noise reduction and voice band enhancement.
Audio Interface NAU88C22YG TR Applications
The NAU88C22YG TR finds application in a diverse range of audio devices. It is ideal for portable audio equipment like MP3 players and portable audio recording devices, as well as smart audio products such as smart speakers, smart headphones, and speech recognition devices. Its low-power design also makes it suitable for automotive audio systems, including in-car entertainment and communication devices. Furthermore, it can be used in home audio equipment, enhancing the performance of home theater systems and hi-fi audio devices.
