NCP2890/D

NCP2890, NCV2890

1.0 Watt Audio Power

Amplifier

The NCP2890 is an audio power amplifier designed for portable

communication device applications such as mobile phone

applications. The NCP2890 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 320 mW to a 4.0

W BTL load from a 2.6 V power supply.

The NCP2890 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.

The NCP2890 contains circuitry to prevent from “pop and click”

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

transitions.

For maximum flexibility, the NCP2890 provides an externally

controlled gain (with resistors), as well as an externally controlled

turn−on time (with the 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 a 9−Pin Flip−Chip CSP (standard

Tin−Lead and Lead−Free versions) and a Micro8

t package.
