Description
The unbalanced-to-balanced board designed with BB's enthusiast DRV134 chip can be used to match the power amplifier board with differential input (balanced input), or it can be used as a dual-channel power amplifier board to change the BTL output. The power supply adopts LM317+LM337 adjustable regulated power supply, and uses 4 imported 2200uf filter capacitors to ensure stable performance.
Parameter
Working voltage: AC dual 5v-16v
DC dual 7v-24v
Board size: 90mm*50mm
Note: The board is shipped and debugged. The power supply defaults to a dual 12v working voltage, which is suitable for use with dual 12v transformers. If you use other voltage transformers, you can properly adjust the output voltage on the board (the positive and negative power supply jumpers should be used when adjusting. Remove the cap to prevent the DRV134 chip from being burnt out by the voltage asymmetry). Generally, the voltage can be adjusted to as many volts as the voltage transformer is used. Adjust the test points: connect one test lead to GND, and the other test lead to jumper pins.
If you don’t want to adjust this voltage, you can directly use a dual 12v-15v transformer to supply power.
