TDA8933B
Class D audio amplier
8.3 Pulse Width Modulation (PWM) frequency
The output signal of the amplier is a PWM signal with a carrier frequency of
approximately 320 kHz. Using a 2nd-order low-pass lter in the application results in an
analog audio signal across the loudspeaker. The PWM switching frequency can be set by
an external resistor Rosc connected between pin OSCREF and VSSD(HW). The carrier
frequency can be set between 300 kHz and 500 kHz. Using an external resistor of 39 k
,
the carrier frequency is set to a typical value of 320 kHz (see Figure 4).
If two or more TDA8933B devices are used in the same audio application, it is
recommended to synchronize the switching frequency of all devices. See Section 14.6 for
more information.
The value of the resistor also sets the frequency of the carrier and can be calculated with

Where:
fosc = oscillator frequency (Hz)
