Monolithic CMOS Analog Switches
Features
The DG401, DG403 and DG405 monolithic CMOS analog
switches have TTL and CMOS compatible digital inputs.
• ON Resistance (Max) . . . . . . . . . . . . . . . . . . . . . . . . . 45Ω
These switches feature low analog ON resistance (<45Ω)
and fast switch time (tON < 150ns). Low charge injection
simplifies sample and hold applications.
The improvements in the DG401/403/405 series are made
possible by using a high voltage silicon-gate process. An
epitaxial layer prevents the latch-up associated with older
CMOS technologies. The 44V maximum voltage range
permits controlling 30VP-P signals. Power supplies may be
single-ended from +5V to +34V, or split from ±5V to ±17V.
• Low Power Consumption (PD) . . . . . . . . . . . . . . . . . . <35µW
• Fast Switching Action
- tON (Max) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 150ns
- tOFF (Max) . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 100ns
• Low Charge Injection
• DG401 Dual SPST; Same Pinout as HI-5041
• DG403 Dual SPDT; DG190, IH5043, IH5151, HI-5051
• DG405 Dual DPST; DG184, HI-5045, IH5145
The analog switches are bilateral, equally matched for AC or
bidirectional signals. The ON resistance variation with analog
signals is quite low over a ±15V analog input range. The three
different devices provide the equivalent of two SPST (DG401),
two SPDT (DG403) or two DPST (DG405) relay switch
contacts with CMOS or TTL level activation. The pinout is
similar, permitting a standard layout to be used, choosing the
switch function as needed.

Application Information
Dual Slope Integrators
Peak Detector
The DG403 is well suited to configure a selectable slope
integrator. One control signal selects the timing capacitor C1
or C2 . Another one selects eIN or discharges the capacitor in
preparation for the next integration cycle.
A3 acting as a comparator provides the logic drive for
operating SW1 . The output of A2 is fed back to A3 and
compared to the analog input eIN . If eIN > eOUT the output
of A3 is high keeping SW1 closed. This allows C1 to charge
up to the analog input voltage. When eIN goes below eOUT,
A3 goes negative, turning SW1 off. The system will therefore
store the most positive analog input experienced.
