PWM OUTPUT CHARACTERISTICS
Test conditions (unless otherwise specified): Input test signal is a full scale 997 Hz signal; MCLK = 12.2880 MHz; Measurement
Bandwidth is 20 Hz to 20 kHz; Sample Frequency = 48 kHz; Test load RL = 8 Ω for stereo full-bridge, RL = 4 Ω for mono parallel
full-bridge; VD = VL = VA = VHP = 1.8V; PWM Modulation Index of 0.85; PWM Switch Rate = 384 kHz.
