Hi All,
In my design, I have to route some analog differential signals come out of a sensor to ADC and DAC through an analog switch. I have selected TS3DS26227 (SPDTx2) switch for the same. So the signals first goes to switch and then routed to ADC or DAC. The load capacitance of the sensor is <5pF whereas input capacitance of TS3DS26227 (switch) is nearly 25pF (Cnc(on)=10.5pF, Ccom(on)=10.5pF and Cno(off)=3.5pF). My question is "Can load capacitance of sensor drive this much capacitance (25pF) of switch?"
I also want to under what is the actual significance of load capacitance in analog domain. Does it mean driving capacity? or does define bandwidth of analog signal?
Can anyone suggest another solution to implement such functionality.
Thanks in advance,
Sachin
