MERUS™ Class-D Audio ICs

Infineon MERUS™ Class-D Audio ICs are multilevel Class-D audio amplifier solutions featuring an embedded digital power management scheme. These ICs consume significantly less input power (~0.25W) and offer high power output in a small form without compromising the produced sound's quality. A power management algorithm dynamically adjusts the switching frequency and modulation scheme to optimize power loss and EMI across the output power range. Flexible power mode profiles allow users to utilize the multilevel switching technique for very low power loss or high audio performance.
