AT42QT2120-XU Overview

In order to package it, Tray materials are used. Surface Mount is used for mounting it on the PCB. Its low package cost accounts for much of 20-TSSOP (0.173, 4.40mm Width)'s popularity in the electronic industry. Providing the 1.8V~5.5V Supply Voltage ensures its normal operation. It is used to input values of Up to 12. As a standard grade, it falls into Type Buttons, Slider, Wheel. A constant -40°C~85°C temperature should be maintained for its operation. As the cost-down performance ratio is the best available on the market, the QTouch? Series offers the best value. A LED driver has a channel of Up to 10. Using terminating 20s, it is constructed. 20 remains the pin number of the component. AT42QT2120 represents the most important part of the gadget. In all cases, the component is powered by a 3.3V-volt supply. The Supply Voltage, Vsup, must be greater than 1.8V. As the reflow temperature reaches its peak, 260. There is a Surface Mount mount that includes it. 12 channels are used for data transmission. It operates on 5.5V voltage.
