Amplificator Bluetooth 4.2 TPA3110 30w+30W PBTL Digital Stereo 12V-24V

TPA3110 2*30W

Parameter:

Power supply voltage: 8-25VDC

Power supply current: 2A or more recommended

Output power: 30Wx2 (@16V)

Dimensions (length, width and height): 53mm X 45mm X 21mm

Interface Description:

Note:When an external audio input is required, the two pads of the "external audio switch" need to be short-circuited.

The board adopts the typical PBTL circuit of TPA3110. It adopts a single power supply with anti-reverse connection. It is very convenient to use a universal adapter and switching power supply for its power supply. Most of the resistance container parts adopt standardized patch technology, which is simple and stable. Design a special interface for the Bluetooth-compatible-compatible audio receiving module, built-in 5V voltage regulator circuit, you can easily DIY Bluetooth-compatible-compatible speakers. The output power is 30W X 2 (@16V), and the board can be connected to 8 ohm and 4 ohm speakers.

Power supply description:

When using a universal adapter and switching power supply, it can be directly connected to the positive and negative poles of the power supply. If a linear transformer is used for power supply, the recommended AC voltage is 9-12V (the highest is AC 15V), and the power is 30-50W linear transformation, and a rectifier filter board is required.
