LVDT Sensor Amplifiers
Analog Devices’ signal conditioning ICs, together with Linear Variable Differential Transformers (LVDTs), can be used to convert mechanical position to a dc voltage. The IC provides both the excitation for the LVDT as well as converting the output to dc level with a user selectable gain. ADI’s LVDT signal conditioners are available to interface with a wide range of LVDTs, including half bridge and standard 4- and 5-wire.
