NCP2990
1.3 Watt Audio Power
Amplifier with Fast Turn On
Time
The NCP2990 is an audio power amplifier designed for portable
communication device applications such as mobile phone
applications. The NCP2990 is capable of delivering 1.3 W of
continuous average power to an 8.0
supply, and 1.0 W to a 4.0
BTL load from a 3.6 V power supply.
The NCP2990 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 NCP2990 contains circuitry to prevent from “pop and click”
noise that would otherwise occur during turnon and turnoff
transitions. It is a zero pop noise device when a single ended audio
input is used.
For maximum flexibility, the NCP2990 provides an externally
controlled gain (with resistors), as well as an externally controlled
turnon time (with the bypass capacitor). When using a 1 F bypass
capacitor, it offers 60 ms wake up time.
Due to its superior PSRR, it can be directly connected to the
battery, saving the use of an LDO.
This device is available in a 9Pin FlipChip CSP (LeadFree).
