AMC1204: What integrator time constant does the modulator have?

user5933871

Part Number: AMC1204

Hello,

To verify my measurement results and unterstand the bandwidth limitations of your modulator and my filter, I want to simulate the modulator as perfect as possible.

Therefore I would need the two integrator time constants of the second order modulator. In the datasheet I only can find the differential input resistance and capacitance.

Is it possible that you can tell me the resistance and the capacitance for the integrators? That would help me a lot.

Thanks in advance,

Julia

Hi Julia,

Thanks for your post and welcome to the forum!

Unfortunately I cannot give out proprietary information not spec'd in the datasheet on a public forum.

If you have additional questions about your bandwidth limitations or understanding, please let me know and I'll do my best to help.

Hi Alex,

thank you for your answer.
Is there any possibility to get the values of the two integrator time constants?
I'm only interested in the ratio between the sampling time of the modulator and the integrator time constant.

Best regards,
Julia

Hi Julia,

As I said before, unfortunately I can't provide this information.
