TSC2006IRTJR datasheet by Texas Instruments

TSC2006IRTJR Frequently Asked Questions (FAQs)

• What is the recommended layout and placement for the TSC2006IRTJR?
  Texas Instruments recommends a 4-layer PCB with a solid ground plane, and placing the device close to the touch sensor electrodes to minimize noise and parasitic capacitance. A good layout practice is to keep the analog and digital signals separate, and use a guard ring around the touch sensor electrodes to reduce noise coupling.
• How do I calibrate the TSC2006IRTJR for optimal performance?
  Calibration involves adjusting the sensitivity and threshold settings to optimize the touch sensor's performance. TI provides a calibration guide in the datasheet, which involves measuring the sensor's capacitance and adjusting the settings accordingly. Additionally, TI's TouchPro GUI software can be used to simplify the calibration process.
• What is the maximum operating frequency of the TSC2006IRTJR?
  The TSC2006IRTJR can operate up to 400 kHz, but the recommended operating frequency is between 100 kHz to 200 kHz for optimal performance and noise immunity.
• How do I handle noise and interference in my touch sensor design?
  To minimize noise and interference, use a shielded cable or a twisted pair for the touch sensor electrodes, keep the sensor away from noisy components, and use a low-pass filter or a shield around the sensor. Additionally, TI recommends using a noise-reducing capacitor between the sensor and ground.
• What is the power consumption of the TSC2006IRTJR?
  The TSC2006IRTJR has a typical power consumption of 1.5 mA at 3.3V supply voltage, making it suitable for battery-powered applications.
