LC717A00AJ-AH

Overview

The LC717A00AJ-AH is a capacitance-to-digital converter manufactured by onsemi, designed for capacitive touch sensing applications. It features eight independent channels and supports both I2C and SPI interface protocols. The device 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. Packaged in a compact SSOP-30 surface-mount format, this component integrates touch sensor functionality into a single LSI solution.

Feature Summary

• Integrates eight-channel capacitance-to-digital conversion for multi-touch detection
• Supports dual communication protocols including I2C and SPI interfaces
• Operates within a wide industrial temperature range suitable for harsh environments

Applications

• Capacitive touch sensor systems

Procurement Notes

Verify current availability status as the component is listed as End-of-Life. Confirm specific ordering suffixes match project requirements. Check for moisture sensitivity handling procedures during storage and assembly. Validate that the SSOP-30 package dimensions fit the target PCB layout constraints before finalizing procurement plans.

Selection Notes

Select this part when eight dedicated touch channels are required with flexible digital interface options. Ensure the system power supply remains within the 2.6 V to 5.5 V operational window. Consider the SSOP-30 footprint for board space limitations. Verify compatibility with existing I2C or SPI bus architectures in the host design.

Part Context

This component belongs to the LC717A00AJ series of touch sensor controllers. It serves as a specialized integrated circuit for converting capacitive changes into digital signals. The device is part of onsemi's broader portfolio of sensor solutions aimed at enhancing user interaction in electronic devices through reliable touch detection capabilities.

Replacement Considerations

Check for direct pin-compatible alternatives within the same family if available. Evaluate other onsemi capacitance-to-digital converters with similar channel counts. Verify interface protocol compatibility with any potential substitute components to ensure seamless integration without major redesign efforts.
