Preliminary Datasheet LPA8003
3-Walts Mono Filter-free Audio Power Amplifier
General Description
The LPA8003 is an audio power amplifier designed for portable
communication device applications such as mobile phone applications.
The LPA8003 is capable of delivering 3W of continuous average power
to an 8 BTL and with less than 10% distortion (THD+N) from a 5.0V
power supply.The LPA8003 provides high quality audio while requiring
few external components and minimal power consumption. It features a
low-power shutdown mode, which is achieved by driving the
SHUTDOWN pin with logic low.
The LPA8003 contains circuitry to prevent from ”pop and click” noise
that would otherwise occur during turn-on and turn-off transitions. For
maximum flexibility, the LPA8003 provides an externally controlled gain
(with resistors), as well as an externally controlled turn-on and turn-off
times (with the bypass capacitor).
The LPA8003 is available in a ESOP8 package.
