MAX14756/MAX14757/MAX14758
Quad SPST +70V Analog Switches
Detailed Description
The MAX14756/MAX14757/MAX14758 are analog
switches with low on-resistance of 10I (max) that con-
duct equally well in both directions. All devices have
a rail-to-rail analog-signal range. They operate with a
single +70V supply in unipolar applications or Q35V dual
supplies in bipolar applications. The bipolar supplies
can be offset and do not have to be symmetrical.
The MAX14756 is a quad NC SPST switch, the MAX14757
is a quad NO SPST switch, and the MAX14758 has two
NO and two NC SPST switches. These switches have 5I
(typ) on-resistances and low on-leakage currents of 5nA
(max). The on-resistance flatness is 0.004I (typ). These
devices are suitable for a multitude of analog-signal rout-
ing and switching applications, and are functonally oper-
ational up to +125°C with increased leakage currents.
Applications Information
Low-Distortion Audio
The MAX14756/MAX14757/MAX14758 switches, having
low RON and very low RON variation with signal ampli-
tude, are well suited for low-distortion audio applica-
tions. The Typical Operating Characteristics show Total
Harmonic Distortion (THD) vs. Frequency graphs for
several signal amplitudes.
Current Through the Switches
The current flowing through every switch must be limited
to Q50mA for normal operation. If the current exceeds
this limit, an internal leakage current flows from the
switch to VSS. Larger input currents do not destroy the
device, as long as the Absolute Maximum Ratings are
not exceeded.
Input-Voltage Clamping
For applications that require input voltages beyond the
supplies rails, the internal input diodes to VDD and VSS
can be used to limit the input voltages. As shown in
Figure 9, series resistors can be employed at the inputs
to limit the currents flowing into the diodes during under-
voltage and overvoltage conditions. Choose the limit-
ing resistors such that the input currents are limited to
IIN_(MAX) = 100mA. The values of the current-limit resis-
tors can be calculated as the larger of RLIM+ and RLIM-.

During an undervoltage or overvoltage condition, the
input impedance is equal to RLIM. The additional power
dissipation due to the fault currents needs to be calcu-
lated. During an overvoltage or undervoltage clamping
condition on one switch input, the other switches of the
MAX14756/MAX14757/MAX14758 operate normally.
Beyond-the-Rail Input
If input voltages are expected to go beyond the supply
voltages, but within the absolute maximum supply volt-
ages of the MAX14756/MAX14757/MAX14758, add two
diodes in series with the supplies as shown in Figure 10.
