3 Description

The LDC1101 is a 1.8-V to 3.3-V, high-resolution

inductance-to-digital converter for short-range, highspeed,

contactless sensing of position, rotation, or

motion, enabling reliable, accurate measurements

even in the presence of dust or dirt, making it ideal

for open or harsh environments.

The LDC1101 features dual inductive measurement

cores, allowing for > 150 ksps 16-bit RP and L

measurements simultaneous with a high-resolution L

measurement which can sample at > 180 ksps with a

resolution of up to 24 bits. The LDC1101 includes a

threshold-compare function which can be dynamically

updated while the device is running.

Inductive sensing technology enables precise

measurement of linear/angular position,

displacement, motion, compression, vibration, metal

composition, and many other applications in markets

including automotive, consumer, computer, industrial,

medical, and communications. Inductive sensing

offers better performance and reliability at lower cost

than other, competing solutions.

The LDC1101 offers these benefits of inductive

sensing in a small 3-mm × 3-mm 10-pin VSON

package. The LDC1101 can be easily configured by a

microcontroller using the 4-pin SPI™.
