LM3886 High Performance Audio Amplifier PCB only

LM3886 High Performance Audio Amplifier PCB Board (Bare PCB)

This PCB is designed for building a mono audio amplifier using the LM3886 IC. Output performance depends on components used and assembly quality.

Output Power:

• Instantaneous peak output power: up to 135 W (depends on supply voltage, load, and heat dissipation)

Performance:

• Signal-to-Noise Ratio (SNR): approximately 92 dB (depends on components and layout)

Working Voltage:

• Dual supply: ±18 V to ±35 V DC
• Recommended transformer: 18-0-18 VAC to 25-0-25 VAC (step-down)

Protection Features (via LM3886 IC):

• Output short-circuit protection (to ground or supply rails)
• Internal current limiting
• Over-voltage protection against transients from inductive loads

Configuration:

• Designed for LM3886 audio amplifier IC
• Requires proper heat sinking for stable operation

Construction:

• Bare PCB (components not included)
• Designed for through-hole components

Board Specifications:

• Compact PCB layout for amplifier integration

Configuration Notes:

• Final output power and performance depend on component selection and power supply design

Intended Use:

• High-fidelity mono audio amplifier construction
• Subwoofer and full-range speaker amplification
• Home audio and DIY amplifier projects
