AD7768 AIN input capacitance

mehdiaghayi on Apr 12, 2022

Hello,

In an application with the maximum frequency of 1kHz can I connect ADA8418A current sense amplifier with just an RC filter to the AD7768 ?
If It's possible without oscillation what is your recommendation.

The ADA8418A datasheet states that the maximum capacitive load can be 500pF.
Can I ask how much would be the input capacitance at the analog inputs for AD7768?

Thank you for your time and consideration,

witht the best regards

Hi,

Apologies for the delay we have contacted the product owner to assist you on this. We'll get back to you as soon as we can.

Thanks,

hi

Depending upon the AD7768 speed of operation you will need a driver in between CSA and AD7768

refer to https://tools.analog.com/en/adcdriver/ to try out and simulate some front ends
