AT42QT2120-SU OverviewIt is packaged using materials from Tube. It is mounted on the PCB using Surface Mount. Low package costs are one of the reasons for 20-SOIC (0.295, 7.50mm Width)'s popularity in the electronic industry. In order for it to operate normally, it requires the 1.8V~5.5V Supply Voltage. We use Up to 12 inputs. Type Buttons, Slider, Wheel is for applications of standard grade. In order for it to operate properly, it should always have a temperature of -40°C~85°C. With the best cost-down performance ratio on the market, the QTouch™ Series provides the best value for your money. This system is powered by --. -- is the resolution of the part. LED drivers use Up to 10 channels. A termination of 20 is used in its construction. The gadget's biggest component has the number AT42QT2120. 3.3V-volt power is always supplied to the component. 1.8V must be greater than Vsup, the supply voltage. Supplier device package 20-SOIC. A Supply Voltage (Vsup) of 5.5V is reached. In the reflow process, the peak temperature is 250. Channel 12 transmits data. Specific uses require a 20 pin. It operates on 5.5, 4.5, 5 V voltage. There is a subcategory Sensors for it.
