The Microsemi LX1725 is part of a new generation of fully integrated stereo class-D amplifiers from Microsemi. The fully integrated halfbridge output for each channel works with both split and single power supply operation. The outputs can be bridged to run in BTL (Bridge Tied Load) mode. In BTL mode, 3-level modulation is used which allow operation without an L-C filter to reduce system cost and area. The LX1725 has >90% efficiency, with typical output power up to 15W+15W in stereo, and 30W BTL into a 4 load with less than 1% THD+N. The amplifier operates over a wide supply voltage range of 6V to 15V split supply or 12V to 30V single supply, and consumes a very little quiescent current.
