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.
