NCP2809: Audio Power Amplifier, Stereo Headphone 135 mW

The NCP2809 is a cost-effective stereo audio power amplifier capable of delivering 135mW of continuous average power per channel into 16Ω loads.The NCP2809 audio power amplifier is specifically designed to provide high quality output power from low supply voltage, requiring very few external components. Since NCP2809 does not require bootstrap capacitors or snubber networks, it is optimally suited for low-power portable systems. NCP2809A has an internal gain of 0 dB while specific external gain can be set with NCP2809B.If the application allows it, the virtual ground provided by the device can be connected to the middle point of the headset. In such case, the two external heavy coupling capacitors typically used can be removed. Otherwise, you can also both outputs in single ended mode with external coupling capacitors.Due to its excellent PSRR, it can be directly connected to the battery, saving the use of an LDO.
