LDC1001/Q1 Inductance to Digital Converters Texas Instruments LDC1001/LDC1001-Q1 Inductance to Digital Converters are automotive-qualified, 4.75V to 5.25V devices, designed for parallel resistance (Rp) and inductance (L) measurements. The LDC1001/LDC1001-Q1 features inductive sensing technology that enables precise measurement of the linear or angular position of metal targets in automotive and industrial applications. Inductive sensing is a contactless, short-range sensing technology that can enable high-resolution sensing of conductive targets in the presence of dust, dirt, oil, and moisture, which can be used by applications in harsh environments.
