Nuvoton-NAU83U25YG

NAU83U25YG is a highly efficient, filter-free, stereo Class-D audio amplifier, which is capable of driving a 4 Ω load with up to 3.0 W output power. This device provides I²C control and I²S audio input with low standby current and fast start-up time.

The NAU83U25YG is ideal for the automotive applications, as it has advanced features like AEC-Q100 grade 2, 80 dB PSRR, 90% efficiency, ultra-low quiescent current (i.e. 2.1 mA at 3.7V for 2 channels) and superior EMI performance.

Target Applications:

Dashboard
VSP (Vehicle Sound for Pedestrians)
AVAS (Acoustic Vehicle Alerting System)
ADAS (Advanced Driver Assist System)
eCall / T-box
