Leakage Considerations
Reverse ESD protection diodes are internally connected
between each analog-signal pin and both V+ and GND. One of
these diodes conducts if any analog signal exceeds V+ or
GND.
Virtually all the analog leakage current comes from the ESD
diodes to V+ or GND. Although the ESD diodes on a given
signal pin are identical and therefore fairly well balanced,
they are reverse biased differently. Each is biased by either
V+ or GND and the analog signal. This means their leakages
will vary as the signal varies. The difference in the two diode
leakages to the V+ and GND pins constitutes the
analog-signal-path leakage current. All analog leakage
current flows between each pin and one of the supply
terminals, not to the other switch terminal. This is why both
sides of a given switch can show leakage currents of the
same or opposite polarity. There is no connection between
the analog signal paths and V+ or GND.
