APPLICATIONS
Switched Signal Powers Analog Switch
The analog switch in Figure 10 derives power from its input
signal, provided the input signal amplitude exceeds 4 V and
its frequency exceeds 1 kHz.
This circuit is useful when signals have to be routed to either
of two remote loads. Only three conductors are required: one
for the signal to be switched, one for the control signal and a
common return.

A positive input pulse turns on the clamping diode D
charges C
chip; operation is satisfactory because the switch requires
less than 1 µA of stand-by supply current. Loading of the
signal source is imperceptible. The DG419’s on-resistance is
a low 100 for a 5 V input signal.
