TDA8932 Based Amplifier Board Module – Overview:
TDA8932 based Amplifier board module is a digital mono amplifier module that provides 35 Watt BTL output. The operating voltage requires a minimum of 10V to a maximum of 30V DC input. This amplifier also supports 4 Ohms to 8 Ohms of speakers that can be directly driven. However, for the best performance, it is recommend to use 24V DC input with an 8 Ohms speaker output. The on-board chip TDA8932 provides high efficiency and does not require any additional heatsinks. It is also call as Bluetooth audio amplifier board tda8932 2x15w since it is use in Bluetooth audio applications.
At full output, the module requires more than 2A of current and switching power supply is recommend to get trouble-free operations.

Interfacing of the TDA8932 Amplifier board is easy. The output can directly connect with the 35W speaker. It is important to use a 35-Watt speaker with this amplifier module. Also, the power input can directly solder with the power input pin. It is also important to use power supply less than 30V rating with a minimum of 2A current rating.
- Public address system
- Sound reinforcement system
- In domestic uses such as home- theatre system
