APPLICATIONS
The DG381B series of analog switches 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.
