LDC1101 Inductance-to-Digital Converter

Texas Instruments' 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 environments.

The LDC1101 features dual inductive measurement cores, allowing for > 150 kSPS 16-bit R_P 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.
