Hi
I'm considering LTC2990.
So, I have a question.
Does LTC2990 have an input Low Pass Filter function?
The measurement results for a noisy signal were very clean.
Or is the ADC a ΣΔ type and does filter processing internally?
Best regards.

Hi Yuya,
The LTC2990 does not have an internal filter but the delta-sigma ADC does effectively implement averaging in the conversion process.

HI, Prasun
Thank you for your reply!
Does that mean that the LTC2990 uses a delta sigma ADC core to perform conversion processing?

Hi Yuya, according to the designer, by oversampling the ADC function itself acts like a low pass filter.
Hi, Prasun
Thank you for your answer!
I understood it.
