Digital Signal Detector Interface IC PS202


Digital Signal Detector Interface IC

PS202
General Description
The detector Integrated circuit is designed for interfacing Passive sensors with
microcontrollers or processors. A single wire Data Out, Clock In (DOCI) interface is
provided for interfacing with a micro-controller. Multiple devices can easily be operated at
the same time. One element connect directly to the inputs. Pull down resistors and DC
decoupling circuitry is integrated on chip. The signal is converted to a 14 bit digital value.
A digital second order Butterworth low-pass filter removes unwanted higher frequency
content. The 14 bit output signal from the filter is supplie
