NCP2811ADTBRGEVB:Stereo Audio Amplifier w/ Adjustable External Gain Evaluation Board
The NCP2809B is a cost-effective fixed gain stereo audio power amplifier capable of delivering 135 mW of continuous average power per channel into 16 ohm loads. This device has been specifically designed to provide high quality output power from low supply voltage, requiring very few external components. The device incorporates a proprietary virtual ground circuit which allows the speakers to be directly connected to the amplifier without the need for bulky DC blocking capacitors. Since NCP2809 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. The NCP2809B has adjustable gain by means of external resistors.
