Texas Instruments LDC1041
the LDC1041 inductance-to-digital converter provides system designers a way to achieve high performance and reliability at a lower system cost than other competing solutions. The LDC1041 is pin compatible with the LDC1000 (16-bit Rp/24-bit L) and the LDC1051 (8-bit Rp). This family of devices offers system designers different resolution options based on their application and system requirements.FEATURES

APPLICATIONS
● Level sensing● Proximity sensing
● Spring motion sensing
● Lateral and angular position sensing
● Metal composition detection 3
DESCRIPTION
Inductive sensing is a contactless, short-range sensing technology enabling high-resolution and lowcost position sensing of conductive targets, even in harsh environments. Using a coil or spring as a sensor, The LDC1041 is available in a 5mm x 4mm WSON16 package. Device programming via SPI allows for easy configuration using a microcontroller.
