15W+15W Stereo Class-D Amplifier Filterless 30W Mono In BTL

The Microsemi LX1725 is part of a new generation of fully integrated stereo class-D Amplifiers from Microsemi. The fully integrated half- bridge 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 spli supply or 12V to 30V single supply, and consumes a very little quiescent current. By Microsemi Corporation
