LDC1101 1.8V, High Resolution Inductance to Digital Converter Evaluation Module


Order now


The LDC1101 evaluation module demonstrates inductive sensing technology to sense and measure the presence or position of a conductive target. The evaluation board includes an example PCB sensor coil that connects to the LDC1101. An MSP430 microcontroller is used to interface the LDC to a host computer. This module is designed to provide the user with maximum flexibility for system prototyping. It is perforated at two locations: one perforation between the PCB sensor coil (LC tank and the LDC1101 and another perforation is between the LDC1101 and the MSP430 interface. The first perforation gives the user flexibility to snap off the PCB coil from the module and experiment with custom sensor coils, and the second perforation allows the user to connect the LDC1101 and sensor coil to a different microntroller system or use multiple sensors in one system. An accompanying GUI allows for maximum flexibility and quick system prototyping.
