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
1
and
charges C
1
. The charge stored on C
1
is used to power the
chip; operation is satisfactory because the switch requires
less than 1 A 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.
