Free-air room temperature 25°C (unless otherwise noted) Measurements were made using TAS5825MEVM 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 frequency set to 384 kHz, the LC filter used was 10 μH / 0.68 μF (Pre-Filter PBTL, the merging of the two output channels in this device can be done before the inductor portion of the output filter, see connect method in Section 10.2.5), unless otherwise noted.
