Discrete Class D Audio Amplifier ICs
Discrete MERUS™ audio amplifier driver ICs with MOSFET and gallium nitride CoolGaN™ 400V e-mode HEMTs
Scalable output power with a unified design platform
Infineon’s discrete audio solutions are scalable to various output power levels, simply by replacing the external MOSFETs or CoolGaN™ e-mode HEMTs of the driver-transistor combinations.
Key parameters for the transistors used in discrete class D audio applications include on-state resistance (RDS(on)), gate charge (QG), and reverse recovery charge (Qrr). Our products are specifically suitable for class D audio applications and optimized for these parameters to achieve maximized efficiency, THD and EMI amplifier performance.
The CoolGaN™ 400V e-mode HEMTs portfolio is specifically built for class D audio requirements, with high performing SMD packages to fully utilize the benefits of gallium nitride.
