3 Description

The LDC5072-Q1 IC is an analog front-end for

contact-less, inductive position sensors targeted for

absolute rotary position in automotive and industrial

applications. The LDC5072-Q1 excites a coil that is

typically printed on a printed circuit board (PCB). The

excitation is coupled back into two sets of receiver

coils on the same PCB using a conductive target

that is placed in close proximity of the PCB. The

conductive target can also be a pattern printed on

another PCB. The coil PCB stays stationary and the

target moves with the motor, actuator, or valve. The

excitation coil generates a secondary voltage on the

receiver coils depending on the position of the target

relative to the receiver coils. A signal representation

of the position is obtained by reading in the voltages

from the receiver coils, processing it, and giving

analog outputs representing the Sine and Cosine

components of the position of the target.
