AT42QT1244-AU OverviewPackaging materials from Tray are used. For mounting on the PCB, Surface Mount is used. The low package cost of 32-TQFP contributes greatly to its popularity in the electronic industry. A normal operation of the 3V~5V is ensured by providing a 3V~5V Supply Voltage. There is a need to use inputs of Up to 24. Standard grade applications fall under Type Buttons. Temperature -40°C~105°C should always be maintained during operation. Due to its excellent cost-to-performance ratio, the QMatrix™ Series represents a great value. In this system, 6.6mA is responsible for supplying the supply current. There is a 10 b resolution on the part. A LED driver's channel is --. 6.6mA is the supply current of the device. AT42QT1244 is the number of the biggest component in the gadget. There is a 32-TQFP (7x7) package on the supplier's device. The data is transmitted over 24 channels. A classification can be made under the Sensors subcategory.
