LDC2112PWR

ADCs/DACs - Special Purpose Overview

The LDC2112PWR is a two-channel inductance-to-digital converter from Texas Instruments, designed for low-power human-machine interface applications. It features a 12-bit resolution and operates on a single supply voltage ranging from 1.71 V to 1.89 V. The device utilizes an I2C interface with a maximum clock frequency of 400 kHz. It functions within a temperature range of -40°C to +85°C and is housed in a 16-pin TSSOP package.

ADCs/DACs - Special Purpose Feature Summary

• Two independent channels for simultaneous touch sensing
• Integrated algorithms for environmental drift compensation and synchronous button detection
• Ultra-low power consumption suitable for battery-operated devices
• Robust EMI performance compliant with CISPR 22 and CISPR 24 standards

ADCs/DACs - Special Purpose Applications

• Smartphones and tablets
• Wearable devices such as smartwatches
• Consumer electronics including smart speakers and VR headsets
• Industrial handheld equipment

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'PWR' corresponds to the 16-pin TSSOP package variant when sourcing. Confirm RoHS compliance status and moisture sensitivity level (MSL 2) requirements for surface-mount assembly processes. Check for any product change notices or end-of-life announcements affecting long-term availability.

ADCs/DACs - Special Purpose Selection Notes

Select this component for designs requiring compact inductive touch solutions without direct electrical contact. Ensure the application environment allows for sufficient material offset detection (>200 nm). Compare channel count requirements against the four-channel LDC2114 if more inputs are needed. Verify I2C bus compatibility with the host microcontroller.

ADCs/DACs - Special Purpose Part Context

This part belongs to the LDC2112/LDC2114 family of inductive touch solutions. It serves as the two-channel counterpart to the four-channel LDC2114. The PWR suffix specifically denotes the Thin-Shrink Small-Outline Package (TSSOP) with a 0.65 mm pin pitch, offering a larger footprint than the DSBGA variant but facilitating easier manual handling during prototyping.

ADCs/DACs - Special Purpose Replacement Considerations

The LDC2112PWT is a pin-compatible alternative in a 16-TSSOP package. For higher channel density, the LDC2114 series offers four channels with similar electrical characteristics.
