Hi team,

Could you tell how fast the output slew rate of TPA2039D1?

Thanks in advance.

Hi, Sawamoto-san,

Approximately, the TPA2039D1 output slew rate is 1mV/us.

Best regards,

Hi Luis,

Thanks for the reply.
Let me confirm again, 1mV/us sounds too slow for 300kHz switching frequency.
Also it looks much faster(5V swing in a couple of nano seconds) when I saw the H-bridge output waveform.
Is there any misunderstanding on me?

Thanks.

Hi, S.Sawamoto,

Do you have a waveform capture in order to get more details about it? You are right, I think this is not the correct value if the switching frequency is 300KHz.

Hi Luis,

Sorry for the late reply.
I've gotten a waveform. I'll send another email to you.
