AT42QT2120-MMH OverviewThe packaging is made from materials from Tray. Mounting the PCB uses the Surface Mount command. 20-VFQFN Exposed Pad's low package cost is a major reason for its popularity in the electronics industry. The 1.8V~5.5V Supply Voltage ensures its normal operation. The inputs of Up to 12 are used. In standard grade applications, it belongs to Type Buttons, Slider, Wheel. A constant -40°C~85°C temperature should be maintained for its operation. Due to its outstanding cost-down performance ratio, the QTouch™ Series is the best in its class. The system's supply current is provided by --. -- is the part's resolution. LED drivers have a Up to 10 channel. Using terminations of 20, it is constructed. Its most important component is AT42QT2120. Power is always provided by a 3.3V-volt supply. It is essential that Vsup exceeds 1.8V, the supply voltage. Supplier device 20-VQFN (3x3) comes in a package. Supply Voltage (Vsup) reaches 5.5 V. Surface Mount mount comes with it. It is transmitted over a channel of 0 bytes. For specific uses, there is a 20 pin. For it to operate, there is no voltage required. The Sensors subcategory can be used to classify it.
