AT42QT1481-ANR Overview
Packaging material from Tape & Reel (TR) is used. Mounting it on a PCB requires Surface Mount. 44-TQFP's low package cost is one of the factors that have made it so popular in the electronic industry. 4.75V~5.25V Supply Voltage is required for the device to operate normally. It is used to input values of Up to 48. As a standard grade, it falls into Type Buttons. You should always keep its operating temperature at -40°C~105°C. QMatrix™ Series offers the best value due to its cost-down performance ratio. A supply current of 13mA is provided to this system. The part is 11 b-resolution. - channels are used by LED drivers. It is constructed using 44 terminations. An 5V volt supply powers the component at all times. Supply voltage, Vsup, must be greater than 4.75V. Supplier device package is 44-TQFP (10x10). At Vsup, maximum Supply Voltage (5.25V) is reached. 48 Channel channels are used for data transmission. 4.75 V to 5.25 V voltage is needed for its operation. Sensors is the subcategory under which it can be classified.
