6.7.1 Bridge Tied Load (BTL) Configuration Curves with 1SPW Mode

Free-air room temperature 25°C (unless otherwise noted.) Measurements were made using TAS5805MEVM board and 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 Modulation mode set to 1SPW mode with Class D Bandwidth = 120 kHz for 576 kHz Fsw and Class D Bandwidth = 175 kHz for 768 kHz Fsw (Listed in Register 0x53) unless otherwise noted.
