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.

Installer for LDC5072-Q1 sensor design tool
This tool generates Gerber files for an evaluation board containing the sensor and LDC5072.
If you would like to have PDF versions of the board files displayed after Gerbers are generated,
then please download the gerber2pdf.exe file from https://sourceforge.net/projects/gerber2pdf/files/
and place it within the installation folder LDC5072_Sensor_Designer/application as gerber2pdf_ALT.exe.
If gerber2pdf_ALT.exe is missing, then the tool will reminder you with the text:
Cannot find Gerber2pdf.exe.
Please download from ti.com or
https://sourceforge.net/projects/gerber2pdf/
if you would like to view the Gerber files as pdfs.
Save the file as application/Gerber2pdf_ALT.exe.
