HWD2171 - 3W Audio Power Amplifier

General Description

3Ω load with less than 10% THD when powered by a 5V power supply (Note 1).

Key Features

  • ew external components and operate on low supply volt- ages from 2.0V to 5.5V. Since the HWD2171 does not require n No output coupling capacitors, bootstrap capacitors, or output coupling capacitors, bootstrap capacitors, or snubber snubber circuits required networks, it is ideally suited for low-power portable systems n Unity-gain stable that require minimum volume and weight. n LLP, MSOP, SO, or DIP packaging Additional HWD2171 features include thermal shutdown pro- n External gain conf.
