AT42QT2640-AU Overview
Packing materials come from Tray. We use Surface Mount to mount it on the PCB. 44-TQFP's low package cost is a major reason for its popularity in the electronics industry. 4.75V~5.25V's normal operation is guaranteed by the 4.75V~5.25V Supply Voltage. It is used to input values of Up to 64. The Type Buttons, Slider, Wheel is suitable for standard grade applications. A constant -40°C~105°C temperature should be maintained for its operation. With the best cost-down performance ratio on the market, the QMatrix? Series provides the best value for your money. 11 b is the part's resolution. 13mA is set as the supply current for the device. It is constructed using 44 terminations. The gadget's biggest component has the number AT42QT2640. An 5V volt supply powers the component at all times. Vsup must be greater than 4.75V for the supply voltage. There is a peak in the reflow temperature of 260. Surface Mount mount includes it. For it to operate, there is no voltage required.
