LDC1614QRGHRQ1

ADCs/DACs - Special Purpose Overview

The LDC1614QRGHRQ1 is a multi-channel inductance-to-digital converter designed for automotive applications. It features four channels with 28-bit resolution, enabling high-precision inductive sensing without magnetic components. The device operates on a single supply voltage ranging from 2.7 V to 3.6 V and supports I2C communication with a maximum clock frequency of 40 MHz. It is qualified under AEC-Q100 standards and functions within an extended temperature range of -40°C to +125°C. The component is housed in a WQFN-16 package.

ADCs/DACs - Special Purpose Feature Summary

• Four independent channels with 28-bit resolution for precise inductance measurement
• AEC-Q100 qualified for automotive reliability requirements
• I2C interface supporting up to 40 MHz clock frequency
• Operates within a 2.7 V to 3.6 V supply voltage range

ADCs/DACs - Special Purpose Applications

• Automotive inductive position sensing
• Non-contact rotary angle detection
• Multi-button touch interfaces in vehicle interiors
• Proximity sensing systems requiring high resolution

ADCs/DACs - Special Purpose Part Context

This part belongs to the LDC161x family of inductance-to-digital converters, specifically tailored for automotive environments as indicated by the Q1 suffix. It shares architectural similarities with the non-automotive LDC1614 but includes additional qualification certifications. The LDC1612 variant offers two channels instead of four, providing a lower channel count option within the same performance class.

ADCs/DACs - Special Purpose Replacement Considerations

The LDC1614RGHRQ1 serves as a direct functional equivalent if available. For non-automotive contexts, the LDC1614RGHR provides identical electrical specifications without automotive qualification. The LDC1612 series offers a two-channel alternative for applications requiring fewer inputs.
