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

  1. 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.
  2. Achieves great output power at low voltages; super energy-saving.
  3. Built-in standby electronic switch, HG buffer amplifier, and short-circuit protection.

Notes:

  1. Do not reverse the battery. The supply voltage should not exceed 5.5V, or the IC will be damaged.
  2. The chip has an HG buffer. You should not alter the parameters of any component on the board; otherwise, unmatched parameters will damage the IC.
  3. You’d better select a wire with a shielding function, which can help resist interference and remove the current sound of clutters.
  4. The output mode is CMOS lamp TTL drive. It would be best not to connect the negative poles of the right and left speakers. This means the four wires should be completely independent, and none should be connected.
