GENERAL DESCRIPTION

The Aeroflex Plainview PCS5035 contains "Five Monolithic" precision current sources designed for

thermistor current monitor and resistive sensor applications. The precision current source

(80µA ±2µA)/Comparatorinputsarecomparedtoanexternalreferenceof0VDC to3VDC. Aprecisioninternal

2.0VDC reference is provided if an external reference is not available. See Figure 1.

The comparator outputs of two (2) PCS5035 can be wired or’ed to provide 10 sensors inputs. Current source

output/comparator inputs of two or more units can be tied together to provide more sensor current. A logic

"high" of 3.4VDC maximum on the enable pin turns on the current source/comparators. Any unused current

source output/comparator inputs can be left open circuit without affecting other I/O’s.
