DESCRIPTION
The DG384A_MIL and DG387A_MIL monolithic CMOS
analog switches were designed for applications in
instrumentation, communications, and process control. This
series is suited for applications requiring fast switching and
nearly flat on-resistance over the entire voltage range.
switches are ideal for battery powered applications, without
sacrificing switching speed. Break-before-make switching
action is guaranteed, and an epitaxial layer prevents latchup.
Single supply operation is allowed by connecting the V– rail to
0 V.
Designed on Vishay Siliconix’ PLUS-40 CMOS process,
these devices achieve low power consumption (3.5 mW
typical) and excellent on/off switch performance. These
Each switch conducts equally well in both directions when on,
and blocks up to the supply voltage when off. These switches
are CMOS and quasi TTL logic compatible.

DG384A_MIL/387A_MIL
Vishay Siliconix
APPLICATIONS
The DG384A_MIL and DG387A_MIL will switch positive
analog signals while using a single positive supply. This allows
their use in applications where only one supply is available.
The trade-offs or performance given up while using single
supplies are: 1) increased rDS(on), 2) slower switching speed.
Typical curves for aid in designing with single supplies are
supplied (see Typical Characteristics). The analog voltage
should not go above or below the supply voltages which in
single operation are V+ and 0 V.
In the integrator of Figure 4, RD controls the discharge rate of
the capacitor so that the pulsed or continuous current ratings
are not exceeded. During reset SW1 is closed and SW2 is
open. Opening SW2 with SW1 also open will hold the integrator
output at its present value.
