The Motion
Sensors (MSI) PCA121S Digital to Analog Converter is a
convenient and low cost device that will provide current
and/or voltage based analog output from pulsed signals
when these are needed to drive plotters, recorders,
printers, and other data acquisition
equipment.
Its intended
use is with sensors, preamplifiers, and other devices
that produce digital, pulsed output when analog output
is also desired.
