AT42QT2161-MMU Overview
Packing materials come from Tape & Reel (TR). Using Surface Mount, it can be mounted on the PCB. 28-VFQFN Exposed Pad is extremely popular in the electronic industry due to its low package cost. In order to ensure its normal operation, it needs the 1.8V~5.5V Supply Voltage. It uses Up to 16 inputs. The Type Buttons, Slider is suitable for standard grade applications. In order for it to operate properly, it should always have a temperature of -40°C~85°C. As the cost-down performance ratio is the best available on the market, the QMatrix?, QSlide? Series offers the best value. In this system, 1.14mA is responsible for supplying the supply current. 10 b is the part's resolution. There are 11 channels on the LED drivers. The current supply of the device has been set to 1.14mA. 28 is the pin number of the component. Supplier devices come in package 28-VQFN (4x4). Surface Mount mount includes it. An electric current of 5.5V volts is required to operate it. As long as it is operating, it should be warmer than -40°C. A maximum Operating Temperature of 85°C is reached at this point.
