ANALOG PASSTHROUGH CHARACTERISTICS
Test Conditions (unless otherwise specified): Input sine wave (relative to full-scale): 1 kHz through passive input filter; PGA and
HP/Line Gain = 0 dB; All Supplies = VA; TA = +25°C; Sample Frequency = 48 kHz; Measurement Bandwidth is 20 Hz to 20 kHz;
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 for stereo full-bridge, RL = 4 for mono parallel
full-bridge; VD = VL = VA = VHP = 1.8V; PWM Modulation Index of 0.85; PWM Switch Rate = 384 kHz; “Required Initialization
Settings” on page 37 written on power up. (Note 9)
VA = 2.5 V
VA = 1.8 V
