LDC1041NHRT

ADCs/DACs - Special Purpose Overview

The LDC1041NHRT is an inductance-to-digital converter manufactured by Texas Instruments, featuring a QFN-20 package. It integrates an 8-bit parallel resistance (Rp) measurement and a 24-bit inductance (L) measurement capability. The device utilizes an SPI interface for data communication and operates within a supply voltage range of 2.7 V to 5.5 V. Designed for precision sensing applications, it supports high-resolution detection of inductive changes, suitable for proximity and position sensing tasks requiring accurate digital conversion of analog inductive signals.

ADCs/DACs - Special Purpose Procurement Notes

Verify the NHRT suffix indicates specific tape-and-reel packaging and temperature grade options. Confirm the manufacturer source directly from Texas Instruments documentation to ensure authenticity. Check for RoHS compliance status as per current product specifications.

ADCs/DACs - Special Purpose Selection Notes

Select this component when 24-bit inductance resolution is required alongside 8-bit resistance monitoring. Ensure the system design accommodates the QFN-20 footprint and SPI communication protocol. Validate that the operating voltage range aligns with the target power supply constraints.

ADCs/DACs - Special Purpose Part Context

This part belongs to the LDC10xx family of inductance-to-digital converters. It shares functional similarities with the LDC1051 but adds parallel resistance measurement capabilities. The series is designed for high-precision industrial and consumer sensing applications.

ADCs/DACs - Special Purpose Replacement Considerations

The LDC1051 serves as a related variant offering 8-bit Rp only without the full 24-bit L measurement. Verify pin compatibility and software register differences before substitution.
