NAU8223 3.1W Stereo Filter-Free Class-D Audio Amplifier 1 Description The NAU8223 is a stereo 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. It has five selectable gain settings (i.e. 0dB, 6dB, 12dB, 18dB and 24dB), which can be controlled by a single gain pin. The NAU8223 is ideal for the portable applications of battery drive, as it has advanced features like 87dB PSRR, 91% efficiency, ultra low quiescent current (i.e. 2.1mA at 3.7V for 2 channels) and superior EMI performance. It has the ability to configure the inputs in either single-ended or differential mode.
