MPC507 Settling Time

Denis A.
Prodigy 60 points

Hello,

I am examining the MPC507 datasheet, for the settling time characteristics for 0.1% and 0.01% (typical values @25C which are provided in the datasheet on Page 2). Additional data is provided under Dynamic Characteristics section on page 6, however no detail is provided on an equivalent circuit used to either simulate of calculate the settling time, taking into account the Access Time.

So, I would really like to better understand the time constant which drives a significant difference in the settling time between 0.1% and 0.01% and in order to do so, I would either require an equivalent circuit (sure a diagram is provided on page 6 of the datasheet, but the CMOS FET devices are not characterized enough while CD and CS (off) are provided and also shown in the test circuit on page 10 ), characteristic equation or the time constant for the component itself.

There are faster performing competitor components, but I do not want to dismiss this part in my design analysis....

If there are additional resources, information or simulation profiles available for TINA, besides the datasheet, that I am missing, please post.

Thanks
