TSC2200IRHB Frequently Asked Questions (FAQs)

• What is the recommended PCB layout for the TSC2200IRHB to minimize noise and ensure optimal performance?
  A good PCB layout for the TSC2200IRHB involves keeping the analog and digital grounds separate, using a solid ground plane, and placing the device close to the touch sensors. Additionally, using a shielded cable or a twisted pair for the touch sensor connections can help reduce noise.
• How do I calibrate the TSC2200IRHB for optimal touch sensor performance?
  Calibration involves adjusting the sensitivity and threshold settings to optimize the touch sensor's performance. This can be done by using the device's built-in calibration routine or by using an external microcontroller to adjust the settings. The datasheet provides more information on the calibration process.
• What is the maximum number of touch sensors that can be connected to the TSC2200IRHB?
  The TSC2200IRHB can support up to 8 touch sensors, depending on the configuration and the type of sensors used. However, the maximum number of sensors that can be connected may vary depending on the specific application and the desired level of sensitivity.
• How does the TSC2200IRHB handle noise and interference from other devices?
  The TSC2200IRHB has built-in noise filtering and shielding to minimize the effects of electromagnetic interference (EMI) and radio-frequency interference (RFI). Additionally, the device's differential sensing architecture helps to reject common-mode noise and interference.
• What is the power consumption of the TSC2200IRHB, and how can I minimize power consumption in my design?
  The TSC2200IRHB has a typical power consumption of 1.5mA in active mode and 1uA in sleep mode. To minimize power consumption, designers can use the device's low-power modes, reduce the clock frequency, and optimize the touch sensor configuration to reduce the number of conversions required.
