5.7.1 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 20-kHz brickwall filter. All measurements taken with audio frequency set to 1 kHz and device PWM frequency set to 384 kHz, 80 kHz Class D Loop Bandwidth, the LC filter used was 10 μH / 0.68 μF, unless otherwise noted.
