www.DataSheet4U.com NCP2821 2.65 W Filterless with Selectable Gain Class D Audio Amplifier NCP2821 is a cost effective mono audio power amplifier designed for portable communication device applications such as mobile phones.
The internal gain setting between 6 dB and 12 dB will also save external gain setting resistors.
To achieve a typical audio mono application, you only need an external capacitor for filtering the power supply.
The NCP2821 processes analog inputs with a PWM technique
