The analog sensors are packaged in the Tape & Reel (TR) for safety reasons. The analog sensors are put into 8-SOIC (0.154, 3.90mm Width) packages to protect the devices from damage. It is necessary for proper operation of this sensor to have 8 pins. It is possible for the analog sensors to produce 3.6V voltage when they are operating. When using analog sensors, the current flowing from the GND terminal should be 12μA.
