Efficiency vs Output Power 6.2 Bridge Tied Load (BTL) Configuration Curves with 1SPW Modulation Free-air room temperature 25°C (unless otherwise noted). Measurements were made using Audio Precision System 2722 with Analog Analyzer filter set to 20kHz brickwall filter. All measurements taken with audio frequency set to 1kHz and device PWM frequency set to 384kHz, 175kHz Class D Loop Bandwidth, the LC filter used was 10μH / 0.68μF, unless otherwise noted.
