AD8170/AD8174 Output Capacitance

Thread Summary

The user is searching for an analog multiplexer with low total input capacitance, specifically for the AD8174. The support engineer clarified that CsOff, CdOff, and CdOn are not specified in the datasheet because the AD8174 is a buffered multiplexer, and the output capacitance is nearly zero or negligible when enabled. The input capacitance is the primary concern, and stray capacitance on the PCB should be considered.

Hi

I am seraching for a an analog multiplexer with a very low "total" input capacitance value.

Output capacitance information exist only for AD8174 /"Output Capacitance Disabled (AD8174) 7.5 pF" page 3 of datasheet) when disable so could I assume that is 0 pF otherwise (It seems strange to me) 

There is no capacitance between input and output or betwwen inputs?

Capacitance from Source to Gnd, CsOff = ?

Capacitance from Drain to Gnd,CdOff = ?

Capacitance for on channel, Cs,Cd on = ?

Best Regards and thanks for your time
