TREBLE AND BASS CONTROL WITH 3D ENHANCEMENT AUDIO POWER DRIVER
August 2012
GENERAL DESCRIPTION
The IS31AP4833 is a treble and bass control with 3D
enhancement audio power driver. The IS31AP4833
provides tone (bass and treble) controls and volume
control as well as a stereo audio power amplifier
capable of delivering 2.8W into 4Ω with less than 10%
THD with a 5V supply.
The IS31AP4833 uses flexible I2C control interface for
multiple application requirements. It also features 3D
sound circuitry which can be externally adjusted via a
simple RC network.
The IS31AP4833 features a 13 steps tone control
(-12dB ~ +12dB, 2dB/step) and a 29 steps volume
control (mute, -42dB ~ +12dB, 2dB/step) for the
headphone and stereo outputs. The volume and tone
are controlled through an I2C compatible interface.
The IS31AP4833 can get independent volume control
for two channels.
IS31AP4833 is available in QFN-36(4mm × 4mm) and
TQFP-48(7mm × 7mm) package. It operates from 3.0V
to 5.5V over the temperature range of -40°C to +85°C.
