Inductive sensing is a non-contact technology that enables the measurement of position, motion, and the properties of metal or conductive targets. It can also detect changes in springs, such as compression, expansion, and deformation. Texas Instruments (TI) has introduced the industry’s first inductive-to-digital converter (LDC), which represents a new category of data converters. According to Jon Baldwin, product line manager for TI’s sensor signal path, this innovative solution uses coils and springs as inductive sensors, offering higher resolution at a lower system cost compared to traditional methods. The LDC also brings improved reliability, greater flexibility, and reduced power consumption.
Jon Baldwin highlights the key technical advantages of the LDC1000 model. First, it provides exceptional resolution: 16-bit resonant impedance and 24-bit inductance level resolution, making it ideal for sub-micron precision applications. Second, the non-contact nature of inductive sensing ensures high reliability by eliminating interference from non-conductive contaminants like oil and dust, thereby extending equipment lifespan. Third, the design offers greater flexibility, allowing the sensor to be placed away from the main electronics, even in areas where a PCB cannot be used. Fourth, the system cost and power consumption are significantly reduced—LDC1000 uses low-cost sensors and conductive targets without the need for magnets. It consumes less than 8.5mW during normal operation and under 1.25mW in standby mode. Finally, the LDC opens up new possibilities for system designers, enabling unlimited creativity in sensor design. The sensor can take many forms, including windings, PCB coils, flexible conductive ink coils, or even springs. The target can be an existing conductor, compressed foil, or conductive ink on a patch, supporting breakthrough applications in axial, lateral, and rotational sensing, as well as event counting. This helps engineers solve complex system challenges with innovative solutions.
System designers can now use TI’s latest WEBENCH inductive sensing design tool to create custom sensor coils in seconds. This online platform simplifies the coil design process and automatically generates configuration settings for the LDC based on coil characteristics, application needs, and performance requirements. The optimized design can then be easily imported into various CAD projects, accelerating the integration of sensor coils into the overall system design.
