CPT212B-A01-GMR Overview
Packaged in materials from Tape & Reel (TR). We use Surface Mount to mount it on the PCB. Despite its low package costs, 20-UFQFN Exposed Pad enjoys a significant amount of popularity in the electronic industry. 1.8V~3.6V's normal operation is guaranteed by the 1.8V~3.6V Supply Voltage. It uses Up to 12 inputs. The Type Buttons is suitable for standard grade applications. Ensure that its operating temperature is always -40°C~85°C. 3.1mA provides this system with its supply current. This is built using terminations of the 20 axis. A 2.4V-volt supply always powers the component. Vsup must be greater than 1.8V for the supply voltage. When Vsup reaches 3.6V, the maximum supply voltage is reached.
