GENERAL DESCRIPTION
FEATURES
The IS31AP2118 is a 15W, dual channel, Class-D
stereo driver in our audio amplifier family. It is suitable
for powering the audio components of various
equipments, including typical consumer electronics,
high performance audio speakers.
Dual 12W, at 4Ω @ 1% THD, VCC=12V
Dual 15W, at 8Ω @ 10% THD, VCC=16V
Mono 20W, at 8Ω @ 10% THD, VCC =18V
90% typical operating efficiency
8V< VIN <26V
IS31AP2118 has several key features which
Filter-less EMI suppression
distinguishes itself from other alternatives on the
market. On-board AGC, EMI suppression, and 90%
typical operating efficiency are key features of this
part. EMI suppression circuit, which eliminates LC,
filters at the outputs. These features simplify customer
design, reduces system cost and PCB area.
Integrated AGC with adjustable power limit
Four selectable, gain preset levels: 20db, 26db,
32db, 36db
High SNR, low THD+N
Thermal and short-circuit protection
Over/under-voltage protection
De-pop circuitry
The IS31AP2118 integrates automatic gain control
function with adjustable power limit. When output
power goes over the power limit, IS31AP2118 can
reduce gain automatically to pull down the output
power, so that keep the output power around power
limit while the input level is high. The IS31AP2118 has
short circuit and thermal protection features integrated
on board.

FUNCTION DESCRIPTION
The IS31AP2118 is a 15W, dual channel, Class-D
stereo driver which is suitable for powering the audio
components of various equipments, including typical
consumer electronics, high performance audio
speakers.
The MUTE pin is an input for controlling the output
state of the IS31AP2118. A logic high on this
terminal will shut down the outputs. A logic low on
this pin enables the outputs.
The gain of the IS31AP2118 is set by two input
terminals, GAIN0 and GAIN1. Different input logic for
GAIN0 and GAIN1 cause input gain in 4 levels
(20dB, 26dB, 32dB, 36dB).
The IS31AP2118 also provides thermal and over
current protection functions to prevent permanent
damage to the device.
