Descriptive summary

Using a practically inaudible automatic power reduction scheme, our Class-D amplifiers avoid over-temperature conditions and, as a result, have no audio holes under every condition. Pin-to-pin compatibility within each family means you get the most practical solutions, while low-cost, single-layer PCB reference designs ensure optimal performance for EMC.
