AT42QT1111-MU Overview
Packaging material from Tape & Reel (TR) is used. In order to mount it on the PCB, Surface Mount is used. Its low package cost accounts for much of 32-VFQFN Exposed Pad's popularity in the electronic industry. The 1.8V~5.5V Supply Voltage ensures the normal operation of the device. The inputs of Up to 11 are used. Type Buttons is for applications of standard grade. 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 12mA. A LED driver's channel is Up to 7. There is a 12mA setting for the device's supply current. Its pin number remains 32. Number AT42QT1111 is the greatest component of the gadget. The package for the supplier device is 32-VQFN (5x5). With the Surface Mount mount, it's included. Over the 11 channel, data is transmitted. There is a 5.5V voltage required for its operation. Operating it should feel warmer than -40°C. It is at this point that the maximum Operating Temperature is 85°C.
