AT42QT2100-MU Overview
Packaging materials from Tray are used. For mounting on the PCB, Surface Mount is used. The low package cost of 32-VFQFN Exposed Pad contributes greatly to its popularity in the electronic industry. A normal operation of the 2V~5.5V is ensured by providing a 2V~5.5V Supply Voltage. There is a need to use inputs of Up to 8. Standard grade applications fall under Type Buttons, Slider, Wheel. Temperature -40°C~85°C should always be maintained during operation. Due to its excellent cost-to-performance ratio, the QTouch™ Series represents a great value. In this system, -- is responsible for supplying the supply current. There is a 14 b resolution on the part. A LED driver's channel is --. Using 32 terminations, it is constructed. AT42QT2100 is the number of the biggest component in the gadget. Power for the component is always supplied by 5V volts. It is necessary for the Supply Voltage, Vsup, to exceed 2V. There is a 32-VQFN (5x5) package on the supplier's device. In this case, the maximum voltage is reached when Vsup (Supply Voltage) reaches 5.5V. It peaks at 260 degrees Celsius during reflow.
