Product details

Sure Electronics AA-AB32291 2x250W IRS2092 Class-D Amplifier Board

This two-channel Class-D amplifier board is based upon the Internal Rectifier AMP7D-200 reference board, using the IRS2092 amplifier IC and the IRFI4020H-117P power MOSFET, and is able to deliver amazing amounts of clean output—up to 250 watts x 2—into 8-ohm loads.

Two 55 to 65 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, dynamic range is a high 100 dB, damping factor is 120, and total harmonic distortion and

 noise is 0.1% at 100 watts into an 8-ohm load. noise is 0.1% at 100 watts into an 8-ohm load.

This amplifier board also includes a myriad of protection features: over current, over/under voltage, DC output, and temperature protection circuits are built-in. A rather small footprint lends itself for use in space limited applications.

Features:
• Stereo Class-D amplifier featuring the IRS2092 amplifier IC
• Dual IRFI4020H-117P digital audio MOSFETs
• Over current, over/under voltage, DC output, and over temperature protection built-in
• Screw-down power input and speaker output terminals
• Robust heatsink for passive cooling
