Protectors as Circuit Elements
Each of the protectors in a MAX4506/MAX4507 may be
used as a switched resistor, independent of the func-
tions of other elements in the same package. For exam-
ple, Figure 4 shows a MAX4506 with two of the
protectors used to protect the input of an op amp, and
the third element used to sequence a power supply.
Combining the circuits of Figures 3 and 4 produces a
delayed action on the switched +15V, as well as
smooth application of signals to the amplifier input.
Figure 5 shows MAX4506 used in front of a MAX338
unprotected 1-to-8 multiplexer. With supplies at ±15V,
VOUT of the MAX4506 clamps to ±15V; VOUT of the
MAX338 goes to ±14V. With supplies off, VOUT goes to
0V while the inputs remain at ±25V.
Use the MAX4506 with a MAX338 to enhance voltage
handling capability (Figure 6). The MAX4506 and
MAX338 share almost equal voltage drops in this con-
figuration. For example, applying ±40V on pins 1 and 2
of the MAX4506 causes a voltage drop of about 26V
across pin 1 of the MAX4506 to pin 4 of the MAX338,
and a voltage drop of about 28V across pin 4 of the
MAX4506 to pin 8 of the MAX338. Similarly, there is a
26V drop from pin 2 of the MAX4506 to pin 5 of the
MAX338. The system’s performance exceeds each
individual part’s specification because of shared volt-
age drops.
Multiplexer and Demultiplexer
As shown in Figure 7, the MAX4506 can be used in
series with the output of a MAX4508 (1-to-8 multiplexer)
to act as multiplexer or demultiplexer. The MAX4508 is a
fault-protected multiplexer whose inputs are designed to
interface with harsh environments; however, its common
output is not fault protected if connected to outside sig-
nals (i.e., demultiplexer use). If the common output can
see fault signals, then it needs to be protected, and the
MAX4506 can be added to provide complete protection.
