The LDC1051 Inductance-to-Digital Converter provides system designers with a way to achieve high performance and reliability with system cost lower than other competing solutions. This article mainly introduces the LDC1051 features, application range, reference design circuit and circuit analysis to help you shorten the design time.
LDC1051 Features:
Inductive sensing is a non-contact, short-range sensing technology that enables high-resolution and low-cost position sensing of conductive targets, even in harsh environments. Use a coil or spring as the sensor. The LDC1051 is pin compatible with the LDC1000 (16-bit Rp/24-bit L) and LDC1041 (8-bit Rp/24-bit L). This family of devices offers different resolution options depending on the system designer's application and system requirements.
- Remote sensor placement (decoupling LDC from harsh environments)
- High durability (by means of non-contact operation)
- Greater flexibility for system design (use coils or springs as sensors)
- Insensitive to non-conductive environmental disturbances (such as dust, dust, oil, etc.)
- Magnetless operation
- Power supply voltage: 5V typical
- Power supply voltage, IO: 1.8V to 5.5V
- Standby current: 250uA typical
- Rp resolution: 8 bits
- LC frequency range: 5kHz to 5MHz
Typical applications for the LDC1051 include: proximity sensing, horizontal sensing, lateral position sensing

Lithium (CAS No.14258-72-1) Li is a silver-white metal with soft, large toughness, good ductility, and the least density metal. The relative atomic mass of lithium is 6.94, the density is 0.534g/cm3, and the melting point is 180°C. It can react with a large number of inorganic reagents and organic reagents. It is extremely unstable in nature, variable in the event of air, and can react violently with water. Because the atomic weight of lithium is very small, the battery with lithium as an anode has the advantages of high energy, high circulation life, small volume, light quality, high charging, and discharging rate, no memory effect, simple maintenance, long storage life, green and environmental protection. In addition, the battery field has become the largest application field of lithium.
