LC717A10PJ-AH

Overview

The LC717A10PJ-AH is a capacitance-to-digital converter LSI designed for electrostatic capacitive touch sensor applications. It features 16 sensing channels and supports I2C and SPI interfaces. The device operates with a supply voltage range of 2.7V to 5.5V and includes built-in noise cancellation functions. It utilizes a QFN package for compact integration in touch control panels.

Feature Summary

• Supports multi-touch detection through 16 independent sensing channels
• Integrates hardware-based noise cancellation for stable operation
• Provides flexible communication via dual interface support

Applications

• Capacitive touch control panels for home appliances
• Touch sensor modules for industrial equipment interfaces
• Multi-touch input devices for consumer electronics

Procurement Notes

Verify the specific suffix AH against official onsemi documentation to confirm pinout and packaging details. Check current availability status as this component family may have discontinuation notices. Ensure compatibility with existing PCB layouts before procurement.

Selection Notes

Select this model when 16-channel resolution is required for complex touch interfaces. Compare channel count and interface options against similar parts like the LC717A10AR if fewer channels suffice. Confirm package type requirements match the target application's space constraints.

Part Context

This part belongs to the LC717A series of capacitance digital converters from onsemi. It shares functional similarities with other variants in the family, differing primarily in channel count and package configuration. The series is widely used in dedicated touch sensor controller designs.

Replacement Considerations

Direct substitutes include LC717A10AR or LC717A10AJ depending on package preference. Verify electrical parameters and pin compatibility before swapping. Consult onsemi PCN documents for any process changes affecting equivalent parts.
