PWM POWER OUTPUT CHARACTERISTICS
AGND = DGND = PGND = 0 V; All voltages with respect to ground; VP = 18 V; RL = 8 Ω for full-bridge, RL = 4 Ω for
half-bridge and parallel full-bridge; PWM Switch Rate = 384 kHz; 10 Hz to 20 kHz Measurement Bandwidth; Per-
formance measurements taken with a full scale 997 Hz sine wave and AES17 filter; Unless otherwise specified.
