Power-Supply Considerations
Overview
The MAX4581/MAX4582/MAX4583 construction is typi-
cal of most CMOS analog switches. They have three
supply pins: V
CC
, V
EE
, and GND. V
CC
and V
EE
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
CC
and V
EE
. If any
analog signal exceeds V
CC
or V
EE
, one of these diodes
will conduct. During normal operation, these and other
reverse-biased ESD diodes leak, forming the only cur-
rent drawn from V
CC
or V
EE
.
Virtually all the analog leakage current comes from the
ESD diodes. 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
CC
or V
EE
and the analog signal. This means their
leakages will vary as the signal varies. The difference in
the two diode leakages to the V
CC
and V
EE
pins consti-
tutes 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 cur-
rents of either the same or opposite polarity.
There is no connection between the analog-signal
paths and GND.
Pin Description
Note:
Input and output pins are identical and interchangeable. Any may be considered an input or output; signals pass equally well
in both directions.
