Procurement Notes
Verify the specific suffix DFR against official Azoteq documentation to confirm tape-and-reel packaging details. Ensure the part number matches the exact configuration required for your design, as suffixes may indicate variations in packaging or testing standards. Cross-reference with authorized distributors for current availability.
Selection Notes
Select this component when a single-channel solution with integrated proximity sensing is required. The IQS231B series is suitable for applications needing low power consumption and small form factor integration. Confirm that the I2C interface compatibility aligns with the host microcontroller.
Part Context
This part belongs to the IQS231B series, which includes variants like IQS231B00000000TSR. The series focuses on simplifying SAR qualification testing while providing robust touch and proximity detection capabilities in compact packages suitable for modern portable devices.
Replacement Considerations
Direct substitutes within the same family include IQS231B00000000TSR. Verify pinout and electrical characteristics before substitution. Other Azoteq sensors like IQS211B offer similar functionality but may differ in package type or channel count.
