Part Number: DS125DF410

Hi Team,

Our customer is asking for the Input Impedance Tolerance for DS125DF410. They seem to have faced impedance trouble in the past using other device.

I can find the input impedance information in the datasheet, however, there is only typical information.

I believe these are not characterized.

Would it be possible to share us the MIN/MAX desige target information ?

If you have any other data which could be shared, it would be greatly appreciated.

Best Regards,

Hi Kawai-San,

I checked with one of the designers. Based on his simulation result, tolerance is from 80-ohm to 120-ohm variation/tolerance. Based on my own ambient testing, I see normally less than 107-ohm but his simulations takes into account lot to lot, across temp, and supply variations.
