9. The PWM driver should be used in captive speaker systems only.
10. Optimal PWM performance is achieved when MCLK > 12 MHz.
LINE OUTPUT VOLTAGE LEVEL CHARACTERISTICS
Test conditions (unless otherwise specified): Input test signal is a full-scale 997 Hz sine wave; measurement bandwidth is 10 Hz
to 20 kHz; Sample Frequency = 48 kHz; test load RL = 10 kΩ, CL = 10 pF (see Figure 2).
