These analog sensors are packaged in the Tape & Reel (TR) for safety protection. Analog sensors are protected from damage by being placed in 8-TSSOP, 8-MSOP (0.118, 3.00mm Width) packages. A 8 pin is required for proper operation of this sensor. Analog sensors should have 12μA current flowing from the GND terminal. Pin number 8 is on it.
