NCP2809 Series NOCAPt 135 mW Stereo Headphone Power Amplifier The NCP2809 is a cost−effective stereo audio power amplifier capable of delivering 135 mW of continuous average power per channel into 16 W 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 externally 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 (Figure 1).
