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

MARKING

DIAGRAM

BTL from 2.6 V power supply. It also provides the control of driving

a single−ended 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

low−power consumption shutdown mode, which is achieved by

driving the shutdown pin with logic Low.

CASE 499AL

The NCP4896 contains circuitry to prevent from “pop and click”

noise that would otherwise occur during turn−on and turn−off

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 turn−on time

(with bypass capacitor).

PIN CONNECTIONS

9−PIN FLIP−CHIP CSP

Due to its excellent PSRR, it can be directly connected to the

battery, saving the use of an LDO.
