8-bit Rp only Inductance-to-Digital Converter with SPI for Inductive Sensing Applications

 

Description

Inductive sensing is a contactless, short-range sensing technology enabling high-resolution and low-cost position sensing of conductive targets, even in harsh environments. Using a coil or spring as a sensor, the LDC1051 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 LDC1051 is pin compatible with the LDC1000 (16-bit Rp/24-bit L) and the LDC1041 (8-bit Rp/24-bit L). This family of devices offers system designers different resolution options based on their application and system requirements.

The LDC1051 is available in a 5mm x 4mm WSON-16 package. Device programming via SPI allows for easy configuration using a microcontroller.

Features

  • Remote Sensor Placement (Decoupling The LDC From
    Harsh Environments)
  • High Durability (By Virtue Of Contactless Operation)
  • Higher Flexibility For System Design (Using Coils
    Or Springs As Sensors)
  • Insensitive to Non-conductive Environmental Interferers
    (such As Dirt, Dust, Oil etc.)
  • Magnet-free Operation
  • Supply Voltage: 5 V, typ
  • Supply Voltage, IO: 1.8V to 5.5V
  • Stand-by Current: 250µA, typ
  • Rp Resolution: 8-bit
  • LC Frequency Range: 5kHz to 5MHz
