onsemi NCP2821
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. The NCP2821 processes analog inputs with a PWM technique that lowers significantly output noise and THD.- Min Voltage : 2.5V
- Max Voltage : 5.5V
- Channels : 1
- Max Operating Temp : 85°C
- Min Operating Temp : -40°C
