The QT60240-ISG is designed for robust, multi-key human-machine interface (HMI) applications, utilizing patented charge-transfer technology

• Multi-Key Sensing

  Supports up to 24 independent touch keys or key matrix configurations, providing flexibility for complex control panel designs.

• QMatrix™ Charge-Transfer Technology

  Patented spread-spectrum, transverse charge-transfer method delivers excellent noise immunity and high sensitivity for reliable touch detection.

• Self-Calibration & Drift Compensation

  Automatically calibrates sensing thresholds and compensates for environmental changes including temperature, humidity, and component aging.

• Advanced Signal Processing
  Adjacent Key Suppression (AKS™): Prevents false triggers from simultaneous or adjacent key presses
  Digital Noise Filtering: Reduces electromagnetic interference (EMI) for stable operation

• Low Power Consumption

  Operates from 1.8V to 5.5V with ultra-low current draw (typically 40µA in low-power mode) and includes auto-sleep functionality.

• Flexible Interfaces
  I²C Interface: Standard 100kHz I²C slave interface for direct communication with host MCU
  Parallel/Shift Register Interface: Supports parallel output for direct key status indication

• Wide Environmental Tolerance
  Temperature Range: -40°C to +85°C
  Panel Compatibility: Detects touches through thick panels (up to 50mm glass, 20mm plastic)
  Moisture Resistance: Reliable performance in high-humidity conditions

Ideal for remote controls, audio systems, smart home devices, kitchen appliances, ovens, washing machines, automotive interior panels, factory interfaces, medical equipment, printers, and multi-function peripherals.
