NAU82011WG

NAU82011WG 2.9 W Mono Filter-Free Class-D Audio Amplifier 1 Description The NAU82011WG is a mono high efficiency filter-free Class-D audio amplifier with variable gain, which is capable of driving a 4Ω load with up to 2.9W output power. This device provides chip enable pin with extremely low standby current and fast start-up time of 4ms. The NAU82011WG is ideal for the portable applications of battery drive, as it has advanced features like 91% efficiency, low quiescent current (i.e. 1.2mA at 3.6V) and superior EMI performance. It has the ability to configure the inputs in either single-ended or differential mode. NAU82011WG is available in MSOP-8 package.
