WONDOM AA-AB32321 Class D Amplifier Module IRS2092 2x87W 8 ohm

The WONDOM AA-AB32321 is a high-power Class D stereo amplifier module based on the Infineon IRS2092 controller, specifically designed for DIY Hi-Fi applications requiring substantial power reserves and excellent efficiency. Powered by a symmetrical supply ranging from ±45V to ±60V DC (±50V recommended), it delivers up to 2x125W into 8Ω at 10% THD+N or 2x87W into 8Ω at 1% THD+N. The module offers high efficiency ranging from 85% to 90%, a frequency response from 20Hz to 20kHz, a typical gain of 31dB, an input impedance of 100kΩ, and an input sensitivity of 839mVrms to reach its rated output power. It features stereo RCA inputs, screw terminals for power supply and speaker outputs, as well as a Shutdown control input. Its design includes a power indicator, overcurrent protection, thermal protection, undervoltage and overvoltage protection, and an optimized heatsink. The module supports a minimum load impedance of 8Ω, consumes approximately 6W at idle, can deliver up to 5.9A at full power, and comes in a 152.4 x 114.3 x 63.5mm format with a weight of approximately 579g.
