The LDC1101 is a 1.8-V to 3.3-V, high-resolution inductance-to-digital converter for
short-range, high-speed, 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
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
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
