NAU82028 3.1W Mono Filter-Free Class-D Audio Amplifier with 2 wire interface gain control 1 Description The NAU82028 is a mono high efficiency filter-free Class-D audio amplifier, 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 3.4ms. The NAU82028 features a highly flexible 2 wire interface with many useful gain settings. The gain can be selected from 12dB to –20.5dB (plus mute) by using 2 wire interface. The NAU82028 is ideal for the portable applications of battery drive, as it has advanced features like 93% efficiency, ultra low quiescent current (i.e. 2.0 mA at 3.6V) and superior EMI performance.
