Monolithic CMOS Analog Switches
The DG401, DG403 and DG405 monolithic CMOS analog switches have TTL and CMOS compatible digital inputs. These switches feature low analog ON resistance (<45) 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. 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.

DG401, DG403, DG405 Application Information
Dual Slope Integrators
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.
Peak Detector
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.
