I am using a tmp36 temperature sensor to measure temperature (with an attiny 85), when I put 5V across the GND and Vs pins of the to92 model the Vout is not 0 (I can't remember the exact value now but perhaps 0.7 or similar).
I have been trying to make a surface mount board and the Vout value using the SOIC version of the tmp36 temperature sensor is only a few mV (or sometimes 0). I thought maybe I had killed the chips when soldering them but I just tried one before it was soldered and it is giving Vout of 0V. I also checked all the other pins in case I had the wrong Vout pin and they were all 0. Is there something obvious I am doing wrong, or could I have gotten fake chips? (bought from two different suppliers though)... will go and check a few more now.
