IQS7225A001QNR

Overview

The IQS7225A001QNR is a sensor interface IC from the Azoteq ProxFusion family, designed for inductive and capacitive sensing applications. It supports six channels configured as inductive-based relative rotational encoders alongside inductive or capacitive buttons. The device operates within a supply voltage range of 1.71 V to 3.5 V and functions across an industrial temperature range of -40°C to +85°C. It utilizes an I2C interface for communication and is housed in a QFN-20 package with dimensions of 3 mm x 3 mm x 0.5 mm.

Feature Summary

• Supports six-channel configuration for inductive-based relative rotational encoder detection
• Capable of detecting both inductive and capacitive button inputs
• Integrates ProxFusion technology for robust sensor signal processing

Applications

• Inductive wheel interfaces with integrated button controls
• Rotational position sensing in industrial or automotive environments
• Human-machine interfaces requiring combined rotary and tactile input

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status via official datasheets. Ensure packaging specifications match project requirements, noting available options include cut tape and reel formats. Validate operating temperature ranges against environmental constraints before integration.

Selection Notes

Select this model when six-channel inductive encoder functionality is required alongside button inputs. Compare channel counts and sensing modalities against alternative IQS7225 variants. Verify package compatibility with PCB layout constraints. Assess power supply stability within the specified 1.71 V to 3.5 V range for optimal performance.

Part Context

This component belongs to the IQS7225A series within the broader ProxFusion portfolio.
