Product details

What this part is and where it fits

The Texas Instruments LDC1612DNTT is a 2-channel inductance-to-digital converter that measures inductance and converts it to a 28-bit digital value over an I²C interface. It is designed for contactless sensing of conductive targets — think position, displacement, or proximity detection in environments where a physical switch or magnetic sensor would wear or drift. The 28-bit resolution gives fine measurement granularity, and the 1k samples-per-second rate is adequate for slow-moving mechanical systems like valve position feedback or linear actuator travel limits. The 12-WSON (4x4) package is a small footprint for space-constrained PCBs.

Frequently asked questions

What is the difference between LDC1612 and LDC1612DNTT?

The LDC1612DNTT is the specific orderable device code for the 12-WSON (4x4) package variant of the LDC1612 family. The base LDC1612 part number may refer to other package options; the DNTT suffix identifies this exact tape-and-reel, surface-mount version.

How do I use LDC1612DNTT for inductive sensing?

Connect an LC resonator (sensor coil and capacitor) to each of the two channels. The LDC1612DNTT measures the resonant frequency shift caused by a conductive target approaching the coil, converting it to a 28-bit digital value read over I²C. The 1k sampling rate is suited for static or slow-moving targets.
