PWM POWER OUTPUT CHARACTERISTICS
Test Conditions (unless otherwise specified): AGND = DGND = PGND = 0 V; All voltages with respect to ground;
T
OutputDly[3:0] = 1111; PhaseShift = 1 for half-bridge, PhaseShift = 0 for full-bridge and parallel full-bridge;
Input Signal: full-scale 997 Hz sine wave through serial audio input port, 48 kHz sample rate; Capacitor values
connected to AFILTA, AFILTB, FILT+, VQ, VD_REG, and VA_REG as shown in
Rate = 384 kHz; 10 Hz to 20 kHz Measurement Bandwidth; Performance measurements taken through AES17 fil-
ter.
