TPA3116D2 Frequency Response

Other Parts Discussed in Thread: TPA3116D2

Hi,

We found that there is mentioned the measurement data of the frequency response on page 9 of TPA3116D2 data sheet as below.
Although the frequency range depends on coefficients of LC filter, can we increase this frequency up to 40kHz as the passband?
In addition, should we set switching frequency above 1000kHz?

Hi, Kato-san,

Yes, you can design the LC filter cutoff freq to 40KHz and/or choose higher PWM freq using AM pins. There is some trade off between higher LC filter cutoff freq and EMC.

Paul.
