5V, High Resolution, Inductance to Digital Converter for Inductive Sensing Applications - LDC1000

LDC1000 (ACTIVE)

5V, High Resolution, Inductance to Digital Converter for Inductive Sensing Applications

Description

Inductive Sensing is a contact-less, short-range sensing technology that enables low-cost, high-resolution sensing of conductive targets in the presence of dust, dirt, oil, and moisture, making it extremely reliable in hostile environments. Using a coil which can be created on a PCB as a sensing element, the LDC1000 enables ultra-low cost system solutions.

Inductive sensing technology enables precise measurement of linear/angular position, displacement, motion, compression, vibration, metal composition, and serval other applications in markets including automotive, consumer, computer, industrial, medical, and communications. Inductive sensing offers better performance and reliability at lower cost than other competitive solutions.

The LDC1000 is the world’s first inductance-to-digital converter, offering the benefits of inductive sensing in a low-power, small-footprint solution. The product is available in a SON-16 package and offers several modes of operation. An SPI interface simplifies connection to an MCU.
