AT42QT1070-MMHR Frequently Asked Questions (FAQ)
-
A good PCB layout for the AT42QT1070-MMHR involves keeping the sensor and the microcontroller close together, using a ground plane to reduce noise, and minimizing the length of the traces between the sensor and the microcontroller. A 4-layer PCB with a dedicated ground plane is recommended.
-
The AT42QT1070-MMHR does not require calibration. It is a self-calibrating capacitive touch sensor that automatically adjusts to the environment and the touch panel. However, it's recommended to follow the guidelines in the datasheet for designing the touch panel and the sensor layout to ensure optimal performance.
-
The maximum operating frequency of the AT42QT1070-MMHR is 100 kHz. However, the recommended operating frequency is 50 kHz to 70 kHz for optimal performance and noise immunity.
-
Yes, the AT42QT1070-MMHR can be used with a 3.3V microcontroller. The sensor's output is compatible with 3.3V and 5V microcontrollers. However, the sensor's power supply voltage (VDD) should be the same as the microcontroller's power supply voltage.
-
To handle EMI with the AT42QT1070-MMHR, use a shielded cable for the sensor's output, keep the sensor and the microcontroller close together, and use a ground plane on the PCB. Additionally, follow good PCB design practices, such as minimizing trace lengths and using bypass capacitors.
