Amplifier module stereo Class D Infineon MA5332 2x150W / 4 Ohm

This Class D stereo amplifier module is based on an Infineon MA5332 amplifier chip. This module has a compact form factor, but develops an output power of up to 2x150W under 4 Ohm. It also integrates a dual NE5532 AOP, a PWM controller, 78M05, 78M10 and 79M05 voltage regulators and 6 x 50V 470uF capacitors. The MA5332 amplifier chip incorporates overvoltage, overcurrent, undervoltage and undercurrent protection. A heat sink is mounted on the MA5332 amplifier chip for efficient heat dissipation. A mute system to prevent noise on power-up completes the package.

Signal input is via a 3-pin PCB connector, while two PCB connectors with screw terminal adapters are located on the output side. Power is supplied to the module via a 3-pin PCB connector, also with screw terminal adapters. This amplifier module accepts a supply voltage range of +/-22V to +/-40V DC 8A.

A +/- 5V secondary output on soldering pads can be used to power a small preamplifier or digital-to-analog converter (DAC) module.
