This Sure Electronics audio amplifier board integrates IR's High Voltage, high performance class D audio amplifier driver IRS2092SPBF and 200V Single N-Channel HEXFET Power MOSFET IRFB4227 to deliver 750 watt of power. This amplifier board supports mono amplification by using one channel half bridge topology.
Sure Electronics AA-AB31431 1x750W IRS2092 4 Ohm Class D Audio Amplifier Board
If you absolutely have to have 750 clean watts of stereo power, look no further than this amplifier board. It integrates high performance class D audio amplifier driver IRS2092SPBF and 200V Single N-Channel HEXFET Power MOSFET IRFB4227 and uses one channel half bridge topology to support mono amplification.
Two 55 to 75 VDC high-voltage power supplies are required for operation; each power supply dedicates its full output potential to a single rail for maximum output. This results in increased high-fidelity output, high dynamic range, low distortion, and a wide 20 to 22,000 Hz frequency response.
