1.1W AUDIO POWER AMPLIFIER WITH ACTIVE-HIGH STANDBY MODE

August 2013

GENERAL DESCRIPTION

The IS31AP4996 has been designed for demanding

audio applications such as mobile phones and permits

the reduction of the number of external components.

It is capable of delivering 1.1W of continuous RMS

output power into an 8 load @ 5V.

An externally-controlled standby mode reduces the

supply current to much less than 2A. It also includes

internal thermal shutdown protection.

The unity-gain stable amplifier can be configured by

external gain setting resistors.

FEATURES

 Operating from V

= 2.7V ~ 5.5V

 1.1W output power @ V

= 5V, THD+N= 1%,

f = 1kHz, with 8 load

 Ultra-low consumption in standby mode (much

less than 2A)

 56dB PSRR @217Hz in grounded mode

 Near-zero click-and-pop

 Ultra-low distortion (0.074%@0.5W, 1kHz)

 SOP-8 and MSOP-8 package

APPLICATIONS

 Mobile phones

 PDAs

 Portable electronic devices

 Notebook computer
