The REF_MA5332BTLSPS reference board is a single BTL channel, 200 W/ch (4 Ω at 40 V) class D audio power amplifier for home audio systems. It features a single BTL channel self-oscillating type PWM for the lowest component count, convenient single power supply and highest performance and robust design. This topology represents an analog version of a second-order sigma-delta modulation, with the class D switching stage inside the loop. The benefit of the sigma-delta modulation - in comparison to the carrier-signal based modulation – is, that all the error in the audible frequency range is shifted to the inaudible upper-frequency range by nature of its operation. Also, sigma-delta modulation enables the designer to apply sufficient error correction.
The REF_MA5332BTLSPS reference board demonstrates how to use the newly launched MA5332MS IC (MERUS™ 2-channel analog input class-D audio amplifier multichip module) with a single power supply and design an optimum PCB layout using an Infineon integrated class D IC. This reference design does not require additional heatsink or fan cooling for normal operation (one-eighth of continuous rated power). The reference design provides all the required housekeeping power supplies for ease of use.
