NCP4894
1.8 Watt Differential Audio
Power Amplifier with
Selectable Shutdown
The NCP4894 is a differential audio power amplifier designed for
portable communication device applications. This feature and the
excellent audio characteristics of the NCP4894 are a guarantee of a
high quality sound, for example, in mobile phones applications. With
a 10% THD+N value the NCP4894 is capable of delivering 1.8 W of
continuous average power to an 8.0
W load from a 5.5 V power
supply. With the same load conditions and a 5.0 V battery voltage, it
ensures 1.0 W to be delivered with less than 0.01% distortion.
The NCP4894 provides high quality audio while requiring few
external components and minimal power consumption. It features a
low−power consumption shutdown mode.
To be flexible, shutdown may be enabled by either a logic high or
low depending on the voltage applied on the SD MODE pin.
The NCP4894 contains circuitry to prevent from “pop and click”
noise that would otherwise occur during turn−on and turn−off
transitions.
For maximum flexibility, the NCP4894 provides an externally
controlled gain (with resistors), as well as an externally controlled
turn−on time (with bypass capacitor).
Due to its excellent PSRR, it can be directly connected to the
battery, saving the use of an LDO.
This device is available in 9−Pin Flip−Chip, Micro−10 and DFN10
3x3 mm packages.
