Overview
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.
NAU8223 is available in Miniature QFN-20 package and TSSOP-20 package.
