The MAX4524/MAX4525’s construction is typical of
most CMOS analog switches. They have two supply
pins: V+ and GND. V+ and GND are used to drive the
internal CMOS switches and set the limits of the analog
voltage on any switch. Reverse ESD-protection diodes
are internally connected between each analog signal
pin and both V+ and GND. If any analog signal
exceeds V+ or GND, one of these diodes will conduct.
During normal operation, these (and other) reverse-
biased ESD diodes leak, forming the only current drawn
from V+ or GND.

Multiplexer and Switch
Virtually all the analog leakage current comes from the
ESD diodes. Although the ESD diodes on a given sig-
nal 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
that leakage will vary as the signal varies. The differ-
ence 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 ter-
minal. This is why both sides of a given switch can
show leakage currents of either the same or opposite
polarity.
