Part Number: TAS5631B

Question 1

I would like to know the relationship between PWM duty cicle of 384kHz input signal and the output voltage.

Question 2

I would like to know lower frequency limit of the output signal. Can this device generate DC voltage ?

Hello,

1) What information are you trying to find out? The relationship is complex.

2) No, this device cannot output DC. I am unsure of the exact low bound but I know at DC the device will stop driving output as it has protection which makes sure the inputs aren't stuck high or low.

Regards,

Thank you very much Adam. I am going to design other type of driver using discrete devices.
