NAU88L25

Ultra-Low Power Audio CODEC for Headphone/Headsets Application

With 124dB Class G Headphone Drive and Advanced Headset Features

Description

The NAU88L25 is an ultra-low power high performance audio codec designed for headphone or headset application

in smartphone, tablet PC, Chromebooks, laptop, game controller, Bluetooth headphones and other portable devices.

It includes one I2S/PCM interface, one high quality stereo DACs, one mono ADC, a Class G stereo headphone

amplifier, and industry leading advanced headset features.

Advanced on-chip signal processing engine including dynamic range compressor (DRC), programmable bi-quad

filters, sidetone and ditial mixers, can maximize audio qualiy enhencements and eliminate the undersirable

frequency components. A frequency locked loop(FLL) is also integrated in the design to support various clocks wih

less external components.

The NAU88L25 has powerful headset detection mechanism, which detects jack insertion / ejection, microphone

presence, speaker impedance, and up-to 8 user defined buttons with long/short key press debouce circuit. It also

supports headphone crosstalk detection/suppression, and automatic microphone & ground detection / switching to

work automatically with different audio jack formats without using external chips or components.

The NAU88L25 operates with analog supply voltages from 1.6V to 1.8V, while the digital core can operate from

1.1V to 1.98V to conserve power. The NAU88L25 is specified for operation from -40°C to +85°C, and is available

in QFN 32 or CSP package with 0.4mm pitch.

Features

 DAC with auto attenuate : 124dB SNR; without

auto mute: 113dB SNR, (A-weighted) @ 0dB gain,
