AMC1100: Output phase shift at low frequencies

robin filer
Prodigy 10 points
Part Number: AMC1100

Hi, i'm using an AMC1100 upstream of an ADC for sensing and need accurate gain and output phase values for it to account for them in the ADC. In Tina i've simulated the spice model and it gives me around -0.06 degrees phase shift at 50hz, is that accurate? If it isn't where can i find the correct values?

Many thanks

    Hi Robin,

    Using a 3 us delay and a 20 ms period I got a 0.054 degree phase shift. So, I believe your -0.06 degree phase shift sounds reasonable. Note, it is subject to change based on maximum specification for signal delay though. Please let me know if you have any more questions.

    Best regards,
