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. ## Sourcing and lifecycle ROHS3 compliant. For current pricing and availability, submit an RFQ; we source through independent distribution and confirm both at quote time.","metaTitle":"LDC1612DNTT Inductance-to-Digital Converter, 28-bit, I²C","metaDescription":"TI LDC1612DNTT inductance-to-digital converter with 28-bit resolution, 2 channels, I²C interface, -40 to 125°C.

The base LDC1612 part number may refer to other package options; the DNTT suffix identifies this exact tape-and-reel, surface-mount version."},{"question":"How do I use LDC1612DNTT for inductive sensing?","answer":"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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LDC1612DNTT","citationPolicyUrl":"https://icboms.com/llms.txt","lastUpdated":"2026-07-17T19:50:00.618Z","lastPublished":"2026-07-17T19:50:00.618Z","indexable":true}}
