Texas Instruments (Dallas, TX) unveiled an inductance-to-digital converter (LDC), a new data converter category that uses coils and springs as inductive sensors. Inductive sensing measures the position, motion, or composition of a metal or conductive target, as well as detects the compression, extension or twist of a spring.
Benefits of LDC technology include sub-micron resolution in position-sensing applications with 16-bit resonance impedance and 24-bit inductance values; contactless sensing that is immune to nonconductive contaminants; and less than 8.5 mW system during standard operation. The 16-pin, 4 × 5 mm LDC1000EVM includes an MSP430F5528 micro-controller (MCU).
