The DG401/403/405 monolithic analog switches were designed
to provide precision, high performance switching of analog
signals. Combining low power (0.35 W, typ) with high speed
(tON: 100 ns, typ), the DG401 series is ideally suited for portable
and battery powered industrial and military applications.
Built on the Vishay Siliconix proprietary high-voltage silicon-gate
process to achieve high voltage rating and superior switch on/off
performance, break-before-make is guaranteed for the SPDT
configurations. An epitaxial layer prevents latchup.
Each switch conducts equally well in both directions when on,
and blocks up to 30 V peak-to-peak when off. On-resistance
is very flat over the full 15-V analog range, rivaling JFET
performance without the inherent dynamic range limitations.
The three devices in this series are differentiated by the type
of switch action as shown in the functional block diagrams.

FIGURE 9. Stereo Source Selector FIGURE 10.Dual Slope Integrator
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.
Band-Pass Switched Capacitor Filter:
Single-pole double-throw switches are a common element for
switched capacitor networks and filters. The fast switching
times and low leakage of the DG403 allow for higher clock
rates and consequently higher filter operating frequencies.

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.
