NCP2809/D
NCP2809 Series
NOCAPt 135 mW Stereo
Headphone Power Amplifier
The NCP2809 is a costeffective 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 lowpower 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).
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.
