Dear Community,
i have used a TS5A22364 in my output path for an analog audio output. In the attachment you will find the schematic and a scope picture.
The Problem:
In the moment of switching the device produces an 1,5V peak on the COM and NO terminal. This peak puls is an loud audible click. I used the TS5A to prenvent the on/off click but now this devices itself produces this peak. I looked up the datasheet and there is the Charge Injection is about 150pC. Together with the output capacitator in my schematic of 10nF there should be a deltaU:
C=Q/U
U=Q/C -> 150pC / 10nF = 15mV!!!
This could be okay.
The scope picture shows the output voltage and the control input.
I hope anybody used this switch for a similar purpose and can tell me if this peak is the normal behavior.
Best regards,
Moritz Bente
PS: To messure the Voltage injected by the TS5A i unconnected the C17 with an without it is the same behavior.
