systems, decreasing approximately 20dB per decade as
frequency increases.
Leakage Considerations
Reverse ESD protection diodes are internally connected
between each analog-signal pin, V+ and GND. One of these
diodes conducts if any analog signal exceeds the
recommended analog signal range.
Virtually all the analog switch leakage current comes from
the ESD diodes and reversed biased junctions in the switch
cell. Although the ESD diodes on a given signal pin are
identical and therefore fairly well balanced, they are reverse
biased differently. Each is biased to either the +Ring or -Ring
and the analog input signal. This means their leakages will
vary as the signal varies. The difference in the two diode
leakages to the +Ring or -Ring and the reverse biased
junctions at the internal switch cell constitutes the
analog-signal-path leakage current.
