AT42QT1481-AN Overview
Packaged 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 48 inputs. The Type Buttons 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 -. This is built using terminations of the 44 axis. 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 5.25V, the maximum supply voltage is reached. 48 Channel-channels transport data. During its operation, 4.75 V to 5.25 V voltage is provided. In the Sensors subcategory, it can be classified.
