WONDOM AA-AB32179 Class D Amplifier Module TDA7492 2x38W 6 Ohm

The WONDOM AA-AB32179 is a compact Class D stereo amplifier module based on the STMicroelectronics TDA7492 chip, designed for DIY audio projects requiring high output power and excellent energy efficiency. Powered by a 10V to 27V DC supply (24V recommended), it delivers up to 2x50W into 6Ω at 10% THD+N or 2x38W into 6Ω at 1% THD+N, while maintaining an efficiency ranging from 90% to 95%. Its compact design integrates audio inputs via solder pads, speaker outputs via screw terminals, and a dedicated power supply terminal block. The module features a power indicator, protection against overcurrent, overheating, and reverse polarity, as well as an optimized heatsink ensuring reliable operation. It offers a frequency response from 20Hz to 20kHz, a typical idle power consumption of 1.9W, standby power consumption as low as 0.2W, and a maximum current draw of approximately 4.5A at full power. Thanks to its compact dimensions of 91.4 x 68.6 x 23.9mm, the AA-AB32179 can be easily integrated into active speakers, DIY amplifiers, or embedded audio systems.
