NAU8325YG

NAU8325YG is a highly efficient, filter-free, stereo Class-D audio amplifier, which is capable of driving a 4Ω load with up to 3.0W output power. This device provides I²C control and I²S audio input with low standby current and fast start-up time.

The NAU8325YG is ideal for the portable applications of battery drive, as it has advanced features like 80dB PSRR, 90% efficiency, ultra-low quiescent current (i.e. 2.1mA at 3.7V for 2 channels) and superior EMI performance.
