LDC1101
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.
