WONDOM AA-AB32174 Class D Amplifier Module TDA7492

The WONDOM AA-AB32174 is a Class D stereo amplifier module based on the STMicroelectronics TDA7492 chip, designed for DIY audio projects, active speakers, and multimedia systems requiring efficient, high-performance amplification. Powered by a DC supply ranging from 10V to 27V, it delivers up to 2x39W into 6Ω at 1% THD+N and can reach 2x50W into 6Ω at 10% THD+N with a 24V power supply. Its Class D architecture provides high efficiency ranging from 88% to 93%, reducing power consumption and heat generation. The module features a power indicator, adjustable gain, as well as overcurrent and overtemperature protection circuits to ensure reliable operation. It also benefits from an optimized thermal design with an integrated heatsink and supports an optional thermally controlled cooling fan. Compatible with speaker loads from 4Ω, it measures 122 x 91 x 39mm and weighs approximately 396g, making it easy to integrate into a wide range of audio projects requiring medium-power stereo amplification.
