LC717A10AJ-AH

Overview

The LC717A10AJ-AH is a capacitance-to-digital converter LSI designed for electrostatic capacitive touch sensor applications. Manufactured by onsemi, this component supports up to 16 channels and features I2C and SPI interface options. It operates within a supply voltage range of 2.6 V to 5.5 V and functions reliably across an extended temperature range from -40°C to +105°C. The device is housed in an SSOP-30 package with SMD/SMT termination. It is classified as a touch sensor IC and is currently marked as end-of-life.

Feature Summary

• Supports multi-channel capacitive sensing for touch interfaces
• Provides flexible digital communication via I2C or SPI protocols
• Operates within wide industrial temperature ranges

Applications

• Electrostatic capacitive touch sensor systems
• Consumer electronics touch controls
• Industrial control panels requiring robust sensing

Procurement Notes

This component is designated as End-of-Life (EOL) by the manufacturer. Availability is restricted to existing stock or last-time buys. Verify specific lot dates and storage conditions carefully due to moisture sensitivity classification. Long-term supply continuity cannot be guaranteed; alternative sourcing strategies should be evaluated immediately for production planning.

Selection Notes

Select this part only if legacy compatibility with 16-channel architectures is required. Ensure system design accommodates the SSOP-30 footprint and voltage levels. Consider newer generation touch controllers for new designs given the EOL status. Verify interface configuration requirements against available pin mappings in the official datasheet before finalizing the bill of materials.

Part Context

Part of the LC717A series of capacitance-digital converters. Related variants include LC717A00AJ-AH (8-channel) and LC717A30UJ-AH (8-channel, AEC-Q100 qualified). The series focuses on converting small capacitance changes into digital data for touch detection logic.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the End-of-Life status, direct pin-compatible replacements must be identified through separate engineering validation. Review onsemi's current portfolio for modern equivalents.
