I tested the LMT84DCKT sample today.
There are 5 pins.
There are 3 gnd pins.
I thought, connecting pin-1 gnd to the ground is enough.
I left pin-2 gnd and pin-5 gnd open.
Temperature is about 26 degrees C, so I expected 892mV at pin-3 output.
But, when I applied 3.3V to pin-4 Vcc, I got 1.43V at pin-3 output.
So, the temperature is less than -50 degrees C?
Must I connect the all 3 gnd pins to the ground?
Hope to get the answer soon!
