Failure Modes
The MAX4533 is not a lightning arrester or surge pro-
tector. Exceeding the fault-protection voltage limits on
NO_ or NC_, even for very short periods, can cause the
device to fail.
Applic ations Information
Ground
There is no connection between the analog signal
paths and GND. The analog signal paths consist of an
N-channel and P-channel MOSFET with their sources
and drains paralleled and their gates driven out of
phase to V+ and V- by the logic-level translators.
V+ and GND power the internal logic and logic-level
translators and set the input logic thresholds. The logic-
level translators convert the logic levels to switched V+
and V- signals to drive the gates of the switches. This
drive signal is the only connection between the power
supplies and the analog signals. GND, IN_, and COM_
have ESD protection diodes to V+ and V-.
S upply Current Reduc tion
When the logic signals are driven rail-to-rail from 0 to
+12V or -15V to +15V, the supply current reduces to
approximately half of the supply current when the logic
input levels are at 0 to 5V.
Power S upplies
The MAX4533 operates with bipolar supplies between
±4.5V and ±18V. The V+ and V- supplies need not be
symmetrical, but their difference can not exceed the
absolute maximum rating of +44V. The MAX4533 oper-
ates from a single supply between +9V and +36V when
V- is connected to GND.
