Procurement Notes
Verify end-of-life status before procurement as the QT113A-ISG is scheduled for obsolescence. Confirm availability through authorized distributors or secondary markets. Ensure compatibility with existing system designs due to discontinuation. Check for alternative components if long-term supply stability is required. Validate packaging specifications against current inventory sources.
Selection Notes
Select this component for single-channel capacitive touch applications requiring low power consumption. Consider the 8-SOIC package for surface-mount assembly constraints. Evaluate the 2.5V to 5.5V operating range against system power supplies. Assess the need for proximity detection features in the target application. Review the 14-bit resolution requirements for touch sensitivity precision.
Part Context
The QT113A-ISG is part of Microchip's Qprox™ family of capacitive touch sensors. It provides a specialized solution for integrating touch controls into embedded systems. The device simplifies design by handling signal processing and calibration internally. It targets applications needing reliable touch input with minimal external components.
Replacement Considerations
QT113A-ISG is discontinued. No official substitute part numbers are publicly confirmed in the provided documentation. Designers should consult Microchip Technology for recommended replacement devices or updated product lines that offer similar functionality and pin compatibility.
