AC ELECTRICAL CHARACTERISTICS
Test Conditions (unless otherwise specified): AGND = DGND = PGND = 0 V; All voltages with respect to ground;
TA = 25°C; VP = 12 V; RL = 8 Ω full-bridge; GAIN1 = 0, GAIN0 = 1; 10 Hz to 20 kHz Measurement Bandwidth; Per-
formance measurements taken with a 997 Hz sine wave and AES17 measurement filter; Stereo Full-Bridge mea-
surements taken through the Full-Bridge Output Filter shown in Figure 4 on page 16.
