Description
NAU8501 Data Sheet
24-bit Stereo Audio ADC with Differential Microphone Inputs emPowerAudio™
The NAU8501 is a low power, high quality audio input system for portable applications. In addition to precision 24-bit stereo ADCs, this device integrates a broad range of additional functions to simplify implementation of complete audio systems. The NAU8501 includes low-noise stereo differential high gain microphone inputs with wide range programmable amplifiers, separate line inputs, and an analog bypass/sidetone line level stereo output.
Advanced on-chip digital signal processing includes a limiter/ALC (Automatic Level Control), 5-band equalizer, notch filter, and a high-pass filter for speech optimization and wind noise reduction.
