NAU82039
3.2W Mono Filter-Free Class-D Audio Amplifier
1 Description
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.
NAU82039 is available in Miniature WCSP-9 (1.21mm x 1.23mm in 0.4mm pitch) package.
