AT42QT2160-MMUR Overview
Packaged in materials from Cut Tape (CT). We use Surface Mount to mount it on the PCB. Despite its low package costs, 28-VFQFN Exposed Pad enjoys a significant amount of popularity in the electronic industry. 1.8V~5.5V's normal operation is guaranteed by the 1.8V~5.5V Supply Voltage. It uses Up to 16 inputs. The Type Buttons, Slider is suitable for standard grade applications. Ensure that its operating temperature is always -40°C~85°C. Based on performance-cost ratios, the QMatrix™, QSlide™ Series offers the best value. 1.127mA provides this system with its supply current. It has a 10 b resolution. A LED driver has a channel of 11. This is built using terminations of the 28 axis. In this gadget, AT42QT2160 is the most significant component. A 5V-volt supply always powers the component. Vsup must be greater than 1.8V for the supply voltage. The package for the supplier device is 28-QFN (4x4). When Vsup reaches 5.5V, the maximum supply voltage is reached. In the reflow process, 260 is the maximum temperature. 16-channels transport data. Specific uses for a 28 pin are provided. During its operation, 1.8, 5.5 V voltage is provided. As long as it is operating, it should be warmer than -40 °C. In this case, the maximum Operating Temperature is 85 °C. In the Sensors subcategory, it can be classified.
