LM73 IC Interface issue

6406.Issue with I2C Communication with LM73.docDear All,

Hi I am using Temperature sensing IC LM73 for temperature sensing application.

I have following issues:

1. The marking on LM73 IC is T730. But no marking or notch available indicating IC pin 1. So I have selected the pin which is to the left of start of marking T730 on IC.

2. I am facing problem with communication with IC is it so that I have made wrong connections as per the nomenclature I have followed as discussed in point 1. The reason is the IC is not acknowledging the address/data sent.
