IQS360-0-QFR

Overview

The IQS360-0-QFR is a capacitive touch sensor IC from Azoteq's ProxFusion series. It features two self-capacitance channels with tracking and SNR boost options. The device operates within a supply voltage range of 1.8 V to 3.6 V and supports an I2C interface. It is housed in a QFN-20 package and functions across a temperature range of -40°C to +85°C.

Feature Summary

• Integrates two self-capacitance sensing channels for touch detection
• Includes built-in tracking and Signal-to-Noise Ratio (SNR) boost capabilities
• Communicates via standard I2C interface for system integration

Applications

• Capacitive touch button interfaces
• Proximity sensing applications
• Slider and wheel input devices

Procurement Notes

Verify the specific suffix 'QFR' against official Azoteq documentation to confirm reel packaging specifications. Ensure compatibility with the required I2C bus speeds and voltage levels. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement plans.

Selection Notes

Select this component when a dual-channel self-capacitance solution with enhanced noise rejection is required. The integrated SNR boost feature makes it suitable for environments with electrical interference. Verify that the QFN-20 package dimensions fit the target PCB layout constraints.

Part Context

This part belongs to the IQS360 family, designed for low-power capacitive sensing. It utilizes Azoteq's ProxFusion technology to provide robust touch and proximity detection. The series is intended for consumer electronics requiring reliable human-machine interaction interfaces.

Replacement Considerations

Check for direct substitutes within the IQS360 series or other Azoteq ProxFusion models. Verify pinout compatibility and software configuration requirements before substituting with similar multi-channel touch controllers.
