The PGA900EVM has an onboard resistive bridge with a potentiometer, letting designers adjust differential input voltages to emulate a pressure sense element.
To complete the measurement system, Macro Sensors supplies LVC Series Support Electronics for the HLR 750 series Position Sensors, which work well with either conventional differential input LVDT signal conditioners or ratiometric signal conditioning circuits.
Normally, connect the output signal to the + differential input and the ground of the device generating the output to the differential input.
The IC includes fail-safe input that prevents metastable conditions when the clock or data input fails to a DC voltage or is not present, thus forcing the differential input to the same potential.
Therefore, when measuring low-level signals, or signals where noise is a significant part of the measurement, or if there is a common-mode voltage, make sure that the USB data acquisition module provides differential input connections.
