NCP2993
1.3 Watt Audio Power
Amplifier with Selectable
Fast Turn On Time
The NCP2993 is an audio power amplifier designed for portable
communication device applications such as mobile phone
applications. The NCP2993 is capable of delivering 1.3 W of
continuous average power to an 8.0 W BTL load from a 5.0 V power
supply, and 1.1 W to a 4.0 W BTL load from a 3.6 V power supply.
The NCP2993 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 NCP2993 contains circuitry to prevent from “pop and click”
noise that would otherwise occur during turn ? on and turn ? off
transitions. It is a zero pop noise device when a single ended or a
differential audio input is used.
For maximum flexibility, the NCP2993 provides an externally
controlled gain (with resistors). In addition, it integrates 2 different
Turn On times (15 ms or 30 ms) adjustable with the TON pin.
