AT42QT1111-AU Overview
Packaged in materials from Tape & Reel (TR). Using Surface Mount, it can be mounted on the PCB. 32-TQFP's low package cost is a major reason for its popularity in the electronics industry. 1.8V~5.5V Supply Voltage is required for the device to operate normally. It is used to input values of Up to 11. As a standard grade, it falls into Type Buttons. You should always keep its operating temperature at -40°C~85°C. Due to its excellent cost-to-performance ratio, the QTouch? Series represents a great value. 12mA provides the supply current for this system. In LED drivers, channels Up to 7 are used. The device's supply current is set to 12mA. Despite this, the pin number of the component remains 32. Number AT42QT1111 is the greatest component of the gadget. The package of the supplier device is 32-TQFP (7x7). The Surface Mount mount contains it. The data is transmitted over 11 channels. Operating it should result in it being warmer than -40°C. A maximum Operating Temperature of 85°C is reached at this point.
