TS3A4751 / Spectrum of Capacitance ,leakage current and Supply current
I am looking into this and will have an answer for you shortly for the capacitance.
For leakage current, these min/max values are already provided in the datasheet.
I will be taking over this for David as he has urgent matters to attend to. Please my answers below:
1. This is still being looked into.
2. The leakage currents are specified in the datasheet as described above. Customer can expect no more leakage than the max value across temp and process. Are these values not acceptable to the customer? Why does the customer need this data?
3. Supply current has no dependency on the input voltage to the switches. regardless of if there is 1 V 2 V etc on the switches the same voltage is applied to gate of the switch to turn it on.
I have checked char data and it correlates with the datasheet for the leakage values specified. Customer should plan on worst case leakage currents specified in datasheet as it is very possible to get parts that have near the max leakage.
This data is taken across temperature and corners.
I apologize for the delay in response to this. I have looked into the char data and discussed with the team on how this data is taken. There is no distribution data taken for this parameter. It is measured across temp and process to find a maximum value. A "buffer zone" is then added to these values to ensure no units reach the customer outside of datasheet values.
