Applications
The DG381A 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 r
DS(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, R
D
controls the discharge rate
of the capacitor so that the pulsed or continuous current
ratings are not exceeded. During reset SW
1
is closed and
SW
2
is open. Opening SW
2
with SW
1
also open will hold
the integrator output at its present value.
