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.

MARKING

DIAGRAM

If the application allows it, the virtual ground provided by the

device can be connected to the middle point of the headset (Figure 1).

In such case, the two external heavy coupling capacitors typically

used can be removed. Otherwise, you can also use both outputs in

single ended mode with external coupling capacitors (Figure 43).

Due to its excellent Power Supply Rejection Ratio (PSRR), it can

be directly connected to the battery, saving the use of an LDO.
