NCP2821 Overview
NCP2821 2.65 W Filterless with Selectable Gain Class−D Audio Amplifier NCP2821 is a cost effective mono audio power amplifier designed for portable munication 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.
NCP2821 Key Features
- Optimized PWM Output Stage: Filterless Capability
- Selectable Gain of 6 dB or 12 dB: No Need for External Gain Setting
- Efficiency up to 90% and Low Quiescent Current
