GENERAL DESCRIPTION

The NAU8315 is a mono high efficiency filter-free Class-D audio amplifier, which is capable of driving a

4Ω load with up to 3.2W output power. This device provides Enable control and I2S audio input with low

standby current and fast start-up time.

The NAU8315 is ideal for the portable applications, as it has advanced features like 80dB PSRR, 91%

efficiency, ultra-low quiescent current and superior EMI performance. NAU8315 is available in a 12 ball

Miniature WLCSP package, a 9 ball Miniature WLCSP package and a 20-pin QFN package.
