NAU82011VG

NAU82011VG 3.1W Mono Filter-Free Class-D Audio Amplifier 1 Description The NAU82011VG 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 3.1W output power. This device provides chip enable pin with extremely low standby current and fast start-up time of 4ms. The NAU82011VG is ideal for battery driven portable applications, as it has advanced features 91% efficiency, 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. NAU82011VG is available in Miniature 9 ball WL-CSP (1.17mm x 1.19mm in 0.4mm pitch).
