Ultra-mini Digital Amplifier Board
This ultra-mini amplifier board features a new high-efficiency digital amplifier effect. With only a 5V input, you can achieve 6W (3Wx2) output power. Its super-slim design allows you to place it in a small plastic box or narrow gaps in digital devices. You can DIY a small portable speaker for your mobile phone, MP3/4 player, and laptop. So, unleash your creativity and start DIYing your sound equipment now!
Technical Parameters
- External Dimensions: 24 x 15.5mm (length x width)
- Operating Voltage: 3.6V~5.5V
- Output Power: 6W (3W x 2, 4Ω)
- SNR: 90dB
- Efficiency: >90%
Advantages
- The PAM8043 efficient digital amplifier chip has a built-in special output processing circuit. To obtain lower EMI, the traditional LC network has been removed.
- Achieves great output power at low voltages; super energy-saving.
- Built-in standby electronic switch, HG buffer amplifier, and short-circuit protection.
Notes:
- Do not reverse the battery. The supply voltage should not exceed 5.5V, or the IC will be damaged.
- The chip has an HG buffer. You should not alter any component’s parameters on the board; otherwise, mismatched parameters will damage the IC.
- You’d better select a wire with shielding, which can help resist interference and reduce the cluttered sound.
- The output mode is CMOS lamp TTL drive. It is best not to connect the left and right speakers’ opposing poles. This means the four wires should be completely independent of one another, and none should be connected.
