MPR084QR2 Overview
Packaging material from Tape & Reel (TR) is used. Mounting it on a PCB requires Surface Mount. 16-VQFN Exposed Pad's low package cost is one of the factors that have made it so popular in the electronic industry. 1.8V~3.6V Supply Voltage is required for the device to operate normally. It is used to input values of 8. As a standard grade, it falls into Type Buttons, Slider, Wheel. You should always keep its operating temperature at -40°C~85°C. A supply current of 1.62mA is provided to this system. Supplier device package is 16-QFN-EP (5x5).
