Description
HXJ8002 Miniature Mono Audio Amplifier Module [3W] package contains of tiny 3 watts mono amplifier, which is based on HXJ8002 single-channel 3W, BTL bridge connected audio power amplifier chip. This chip is a power amplifier with low power supply, that can provide 3W average audio power for a 3Ω BTL load with low harmonic distortion (under 10% threshold distortion at 1KHz) from a 5V DC power supply. This chip can amplify audio signals without any coupling capacitors or bootstrap capacitors.
The module can be supplied by a 2.0V up to 5.5V DC with 10mA operating current (0.6uA for typical standby current) power source and produce a powerful amplified sound into a 3Ω, 4Ω, or 8Ω impedance speaker. This module has an improved pop and clicks circuitry for reducing significantly the transition nose at the powering on and off moment. Tiny size besides high efficiency and low power supplying make it applicable in widely portable and battery-powered projects and microcontroller and Arduino boards.
