Overview

HG4871 is a 3W mono Class AB audio power amplifier. Operating voltage range: 1.9–5.5V. In BTL bridge configuration with a 5V supply, it delivers an average output power of 3.0W into a 4Ω load at THD less than 10%. In shutdown mode, the typical supply current is less than 0.5μA. Designed to deliver full-power, high-fidelity audio output with minimal external components, requiring no output coupling or bootstrap capacitors. Available in DIP-8, SOP-8, ESOP-8, MSOP-8, EMSOP-8, and DFN-8 packages for compact board layout, making it ideal for mobile phones and portable devices where low voltage and low power consumption are essential.

Applications

Mobile phones (cell phones, etc.)
Amplifiers, Bluetooth speakers, etc.
Radio receivers
GPS, radar detectors, dash cams
Voice toys, etc.
