TDA8932 35W Class D Mono Low Frequency Amplifier

The TDA8932 is a high quality, single channel, low frequency D-class amplifier. To date, the use of pulsed audio frequency amplifiers has greatly expanded. Thanks to this, this module can be used in speakers, home theater, car speakers, etc. The amplifier board has a small size and a wide supply voltage range, so it can also be used in portable speakers.

The module is designed on the TDA8932 chip. The microcircuit has 32 outputs and is made in the SO32 package. The TDA8932 is a powerful class D amplifier. The microcircuit has DMOS (Diffusion Metal Oxide Semiconductor) transistors that act as output switches. The power rating of the amplifier is 35W into an 8 ohm load. The maximum output current of the module is 8 A. The conversion frequency of the module is 320 kHz, which provides an extremely low distortion factor (less than 0.1%). The efficiency of the module is over 90%. Thanks to all these advantages of the amplifier, it is capable of producing good sound quality.

Also, the module has protection against: short circuit (short circuit) and overheating.

The TDA8932 amplifier board has 6 pins:

IN+: input signal
IN-: common wire of the connected device
OUT+: output signal
OUT-: speaker common wire
POWER+: Amplifier supply voltage
POWER-: "ground"

Power is supplied from the power supply or other external power source. The power supply voltage range of the amplifier is 10 to 30 V, but 12 to 24 V is recommended.
