Product pin definition and function:
· CS: chip select (floating or high, boot; low, shutdown)
· IN-: audio signal input negative
· IN +: audio signal input positive
· GND: Power ground
· VCC: Positive power supply
· SP +: audio signal output positive, then horn +
· SP-: audio signal output positive, then speaker -
Precautions:
1. Power supply positive and negative can not be reversed, the power supply voltage can not exceed 5.5V, as long as there is one case, IC burned;
2. The chip has a high gain buffer, can not change any component parameters on the board, does not meet the parameters will lead to IC damage;
3. Enter the line as far as possible with a shielded line, you can play a role in anti-interference, to eliminate the clutter current sound.
