HXJ8002 Mini Amplifier Module

Specifications:

• Chip: Onboard HXJ8002 BTL (bridge-tied load) audio power amplifier chip.
• Channels: Single (mono).
• Output Power:
  • 3W for a 3Ω load.
  • 2.5W for a 4Ω load.
  • 1.5W for an 8Ω load.
• Operating Voltage: 2.0V to 5.5V, making it suitable for battery-powered devices.
• Standby Current: 0.6µA (typical), ensuring efficient power usage.
• Dimensions: Approximately 19.8mm x 14.2mm.
• Distortion: Low total harmonic distortion (THD), with less than 0.5% at 1W output with an 8Ω load.
• Other features: Built-in thermal protection to prevent overheating. 

Applications:

• Portable audio devices: Enhancing the sound from MP3 players or smartphones.
• DIY audio projects: Creating custom audio systems.
• Embedded systems: Integrating audio output into small electronics.
• Portable speakers: Powering small, battery-operated speakers.
• Educational kits: Used in learning modules related to audio electronics.

• Space-saving design: The small form factor requires minimal external components, simplifying circuit design.
• Minimalistic design: It doesn’t require a coupling capacitor, bootstrap capacitor, or buffer network, which reduces costs and saves board space.
• Energy-efficient: The low standby current is great for battery-powered projects.
