Applications
voltage. The supply voltage is supplied from J2 thru JP3 to VDD1, then the device regulates +5V
on VDD using the onboard FET giving a stable output over varied supply voltage.
voltage; this is used when the device output is tied to an A/D converter sharing the same supply
and ground reference. A 4.5V to 5.2 V supply voltage is supplied thru VDD and VDD1 tied
together.
use as a 2-wire analog sensor. VDD is regulated by the onboard FET from the supply (7V to
35V) thru VDD1. JP3 must be open to separate the interface circuit supply thru J2 from the
device current supply thru VDD1. The device supply ground must be floating with respect to the
interface circuit ground. DO NOT CONNECT CMN to GND.
