For safety reasons, these analog sensors are enclosed in the Tape & Reel (TR). To protect analog sensors from damage, they are put into 8-SOIC (0.154, 3.90mm Width) packages. In order to operate properly, this sensor has 8 pins. Electronic part with 8 terminations. Analog sensors should have a current flowing from the GND terminal of 50μA. A sensor like this can be powered with 410μA current in theory.
