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 x 1.645mm 16-pin WLCSP pack-

age and in the 3mm x 3mm 16-pin QFN package, and is

specified for operation over the -40°C to +85°C ambient

temperature range.

Typical Application

1. When independent control is used, the device ground and the audio source ground should be connected together.
