PWM OUTPUT PERFORMANCE CHARACTERISTICS
(Logic “0” = GND = 0 V; Logic “1” = VLS = VLC; VD = 2.5 V; DAI_MCLK = 12.288 MHz; XTAL= 24.576 MHz; PWM
Switch Rate = 384 kHz; Fs = 32 kHz to 192 kHz; Measurement bandwidth is 10 Hz to 20 kHz unless otherwise
specified; Performance measurements taken with a full-scale 997 Hz.)
