AT42QT1481-AU Overview
In order to package it, Tray materials are used. In order to mount it on the PCB, Surface Mount is used. Despite its low package costs, 44-TQFP enjoys a significant amount of popularity in the electronic industry. Providing the 4.75V~5.25V Supply Voltage ensures the device's normal operation. There are inputs of Up to 48. In standard grade applications, it belongs to Type Buttons. The temperature should always be kept at -40°C~105°C during operation. QMatrix? Series offers the best value due to its cost-down performance ratio. 11 b represents the part's resolution. 13mA is the supply current of the device. Using 44 terminations, it is constructed. 44 remains the pin number of the component. The gadget's biggest component has the number AT42QT1481. An 5V volt supply powers the component at all times. In the reflow process, 260 is the maximum temperature. This is included in the Surface Mount mount. Over the 48 channel, data is transmitted. For it to operate, there is no voltage required.
