TAS5782M: How to Change PWM Switching Frequency

Sadanori Kato

Part Number: TAS5782M

Hi,

Could you please tell me how to change the pwm switching frequency ?
Is my understanding correct that the pwm switching frequency can be changed by changing the external resistors as mentioned on page 51 of TAS5782M data sheet ?

Best regards,

Hi Kato-san,

Your understanding is right. Please refer to 9.3.6: Adjustable Amplifier Gain and Switching Frequency Selection in Page50 for more details.

Please make sure that switching frequency is dependent on the internal synchronizing signal Fsync that is dependent on the sample rate.
You can refer to table 13 for more details too.
