Figure 17. 1SPW Mode Modulation

7.3.13 AM Avoidance EMI Reduction

To reduce interference in the AM radio band, the TPA3116D2-Q1 has the ability to change the switching

frequency via the AM[2:0] pins. The recommended frequencies are listed in Table 7. The fundamental frequency

and its second harmonic straddle the AM radio band listed. This eliminates the tones that can be present due to

the switching frequency being demodulated by the AM radio.
