Using a coil or spring as a sensor, 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. The LDC1041 is availabl...
