DUAL 2.5W AUDIO POWER AMPLIFIER AND STEREO HEADPHONE DRIVER
WITH TONE CONTROL AND 3D ENHANCEMENT
January 2012
GENERAL DESCRIPTION
The IS31AP4832 is a monolithic integrated circuit that
provides tone (bass and treble) controls as well as a
stereo audio power amplifier capable of delivering
2.5W (Typ.) into 4or 1.7W (Typ.) into 8with less
than 10% THD with a 5V supply. The IS31AP4832
uses flexible I2C control interface for multiple
application requirements.
The IS31AP4832 also features 3D sound circuitry
which can be externally adjusted via a simple RC
network. The headphone amplifier features Output
Capacitor-less (OCL) architecture that eliminates the
output coupling capacitors required by traditional
headphone amplifiers.
The IS31AP4832 features a 13 step tone control for
the headphone and stereo outputs. The device mode
select and Tone are controlled through an I2C
compatible interface.
Thermal shutdown protection prevents the device from
being damaged during fault conditions. Superior click
and pop suppression eliminates audible transients on
power-up/down and during shutdown.
