DATA SHEET
AAT5102
2.5W/Ch Stereo Class D Audio Power Amplifier
General Description
The AAT5102 is a high efficiency, high performance ste-
reo class D audio amplifier. It is designed to operate in a
wide supply voltage range from 2.5V to 5.5V and is tar-
geted to deliver up to 2.5W output power to a 4Ω load
with× 5V power supply. Efficiency of up to 90.5% makes
it ideal for portable applications.
The AAT5102 has four adjustable amplifier gains with 6,
12, 18 and 24dB programmed by two external pins. Two
shutdown control pins are employed to control the left
and right channels independently.
The AAT5102 also integrates over-temperature protec-
tion circuitry to prevent internal junction temperature
over-heating.
The AAT5102 is offered in a Pb-free, thermally enhanced,
space-saving 1.645mm × 1.645mm 16-pin WLCSP pack-
age and in the 3mm × 3mm 16-pin QFN package, and is
specified for operation over the -40°C to +85°C ambient
temperature range.

Application Information
The AAT5102 is a closed loop pulse-width-modulated
switch mode power amplifier for driving bridge-tied load.
It features high performance with high efficiency, high
SNR and low THD+N. It also offers built-in over-temper-
ature protection.
Gain Setting
The AAT5102 voltage gain can be programmed to 6, 12,
18 and 24dB via two inputs, PGA1 and PGA0. See Table
1 for gain setting.
