NAU82039VG

The NAU82039 is a mono high efficiency filter-free Class-D audio amplifier with 12dB of fixed gain, which is capable of driving a 4Ω load with up to 3.2W output power. This device provides chip enable pin with extremely low standby current and fast start-up time of 4ms.

The NAU82039 is ideal for the portable applications of battery drive, as it has advanced features like 90dB PSRR at 217Hz, 93% efficiency, ultra low quiescent current (i.e. 1.25mA at 3.6V) and superior EMI performance. It has the ability to configure the inputs in either single-ended or differential mode.
