AT42QT2640-AU OverviewPackaged in materials from Tray. We use Surface Mount to mount it on the PCB. Despite its low package costs, 44-TQFP enjoys a significant amount of popularity in the electronic industry. 4.75V~5.25V's normal operation is guaranteed by the 4.75V~5.25V Supply Voltage. It uses Up to 64 inputs. The Type Buttons, Slider, Wheel is suitable for standard grade applications. Ensure that its operating temperature is always -40°C~105°C. Based on performance-cost ratios, the QMatrix™ Series offers the best value. 13mA provides this system with its supply current. It has a 11 b resolution. A LED driver has a channel of --. The current supply of the device has been set to 13mA. This is built using terminations of the 44 axis. In this gadget, AT42QT2640 is the most significant component. A 5V-volt supply always powers the component. Vsup must be greater than 4.75V for the supply voltage. The package for the supplier device is 44-TQFP (10x10). When Vsup reaches 5.25 V, the maximum supply voltage is reached. In the reflow process, 260 is the maximum temperature. With the Surface Mount mount, you get it included. 64 Channel-channels transport data. Specific uses for a 44 pin are provided. During its operation, 5.25V voltage is provided. In the Sensors subcategory, it can be classified.
