NCP4896
1.0 Watt Audio Power
Amplifier with Earpiece
Driving Capability
The NCP4896 is an audio power amplifier designed for portable
communication device applications such as mobile phones. This part
is capable of delivering 1.0 W of continuous average power to an
8.0
W BTL load from a 5.0 V power supply and, 250 mW to a 4.0 W
BTL from 2.6 V power supply. It also provides the control of driving
a singleended earpiece and delivers 90 mW from a 5.0 V power
supply to a 32
W load.
This device provides high quality audio while requiring few
external components and minimal power consumption. It features a
lowpower consumption shutdown mode, which is achieved by
driving the shutdown pin with logic Low.
The NCP4896 contains circuitry to prevent from “pop and click”
noise that would otherwise occur during turnon and turnoff
transitions. It is also efficient when switching modes from BTL to SE
and SE to BTL.
For maximum flexibility, the part provides an externally controlled
gain (with resistors), as well as an externally controlled turnon time
(with bypass capacitor).
Due to its excellent PSRR, it can be directly connected to the
battery, saving the use of an LDO.
