TDA8932 Based Audio Amplifier Board

TDA8932 based Audio Amplifier Board module is a digital mono amplifier module that provides 35 Watt output. This board uses a high-performance digital amplifier TDA8932 chip. Due to the small size, it is easily mounted in any small space-based DIY audio amplifier project. It has high efficiency, high power, good sound quality without additional installation of a radiator. Very suitable for the transformation of active speakers, electroacoustic project implementation, product development, and other audio applications.

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 recommended 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 commonly known as Bluetooth audio amplifier board tda8932 2x15w since it is used in Bluetooth audio applications.


At full output, the module requires more than 2A of current and switching power supply is recommended to get trouble-free operations.


Interfacing diagram

Interfacing of the TDA8932 Amplifier board is easy. The output can be directly connected with the 35W speaker. It is important to use a 35-Watt speaker with this amplifier module. Also, the power input can be directly soldered with the power input pin. It is also important to use power supply less than 30V rating with a minimum of 2A current rating.
