MTCH112-I/SN SMD IC

MTCH112 Dual Channel Proximity Touch IC

The MTCH112 uses a sophisticated optimization algorithm to actively eliminate noise from the signal .While the noise level is being measured, the requirements for a proximity or touch detection are updated to reflect the degree of uncertainty in the readings. When a press is detected for the first time ,the threshold is automatically calibrated to choose a smart threshold for the ‘release’ and next press. This creates a system that dynamically optimizes the sign alto-noise ratio for its environment.

DNA solutions, Nashik has various types of Touch IC's. Check out our complete collection of  Touch Sensor IC's.

• Capacitive Proximity Detection System:
  

• High Signal to Noise Ratio (SNR)
  

• Adjustable sensitivity
  

• Noise Rejection Filters
  

• Scanning method actively optimized to attenuate strongest noise frequencies
  

• Automatic calibration with optional user presets
  

• Dynamic threshold management adjusts sensitivity of sensor based on the level of environmental noise
  

• Constant press calibration tracks the expected offset when the sensor is pressed and adjusts the threshold to automatically achieve the best press/release behavior
  

• User-defined “minimum shift” values specify the lowest amount of signal change to activate a state transition. Automatic thresholds never decrease below these settings.
  

• Automatic Environmental Compensation
  

• Stuck release mechanism
  

• No Required External Components
  

• Low-Power mode: Highly Configurable Low-Power mode
  

• 1 ms to 4s Sleep interval between sensor samples
  

• Response Time as Low as 10 ms
  

• Hardware Error Detection notifies if either sensor is shorted to VDD, VSS or the other sensor
  

• Operating Voltage Range: 1.8V to 3.3V
  

• Operating Temperature: 40°C to +85°C
