IS31AP2111 2×20W STEREO DIGITAL (I2S) AUDIO AMPLIFIER WITH 20 BANDS EQ FUNCTIONS
Integrated Silicon Solution, Inc. – www.issi.com 1 Rev. A, 12/19/2014
DESCRIPTION
The IS31AP2111 is a digital I2S interface audio amplifier capable of driving a pair of 8Ω speakers at 20W when operating from a 24V supply. Due to its Class-D output drive stage, it can operate without an external heat-sink or fan.
The IS31AP2111 integrates advanced audio processing capabilities, such as volume control, 20 bands speaker EQ, audio mixing, 3D surround and Dynamic Range Control (DRC). These functions are fully programmable via a simple I2C control interface.
Robust protection circuits are provided to protect the IS31AP2111 from damage due to accidental erroneous operating conditions. Because of its digital design, the IS31AP2111 is more tolerant to noise and PVT (Process, Voltage, and Temperature) variation than the analog Class-AB or Class-D audio amplifier counterpart. It has built-in anti-pop circuitry for pop free operation during power ON.

PROCEDURE
The IS31AP2111 demo board is fully assembled and tested. Follow the steps listed below to verify board operation.
Caution: Do not turn on the power supply until all connections are completed.
1) Connect the ground terminal of the power supply to the GND and the positive terminal to the VCC. Or connect DC power to connector (DC IN).
2) Connect a pair of 8Ω speakers to the SPK_L (RCA connector) and SPK_R (RCA connector).
3) Connect an audio source to the audio connector AUDIO IN (3.5mm stereo connector).
4) Turn on the power supply. 5) IS31AP2111’s default setting is mute. Please
program the following registers via the I2C interface to disable the mute:
a) When use A/D converter(U2) I2S data output for IS31AP2111, the evaluation board must set the MCLK/FS to 256x and Sampling Frequency to 32/44.1/48kHZ, write value (04h) to register 0x01 to set the state.
b) 02h State Control 3 Register: To disable the Master mute: clear bit D3 To disable the individual channel mutes: clear D2:D1 bits.
c) 03h Master Volume Control Register: To set the Master volume write a value to bits D7:D0, To set the individual channel volumes: write a value to registers 0x04-0x05.
d) Please refer to the IS31AP2111 datasheet for register values used in programming features such as mute, volume, bass/treble tone, surround sound, equalization, etc.
