AT42QT1244-MUR OverviewPackaging material from Tape & Reel (TR) is used. Mounting it on a PCB requires Surface Mount. 32-VFQFN Exposed Pad's low package cost is one of the factors that have made it so popular in the electronic industry. 3V~5V Supply Voltage is required for the device to operate normally. It is used to input values of Up to 24. 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 6.6mA is provided to this system. The part is 10 b-resolution. -- channels are used by LED drivers. There is a 6.6mA setting for the device's supply current. It is constructed using 32 terminations. There is a AT42QT1244 component on the gadget that is the largest. Supply voltage, Vsup, must be greater than 3V. Supplier device package is 32-QFN (5x5). At Vsup, maximum Supply Voltage (5V) is reached. A reflow temperature peak is NOT SPECIFIED. Including it in the Surface Mount mount is a great feature. 24 Channel channels are used for data transmission. Specific uses are addressed by a 32 pin. Sensors is the subcategory under which it can be classified.
