Multiplexor Operation
T
he DC peak output for measurement is se-
lected using the reset and strobe pins. Reset
high resets the multiplexor. Reset low enables
t
he strobe pin. After the first strobe leading
edge, 63Hz output is on OUT. Each additional
strobe leading edge advances the multiplexor
one channel (63Hz, 160Hz, 400Hz, 1kHz,
2.5kHz, 6.25kHz, 16kHz etc.) and this will re-
peat indefinitely. The multiplexor read rate is
also the output decay time control. Each read
decays that channel approximately 10%. The
strobe timing is shown below:
