i know there is an 8 pin and 3 pin option with an NDV or LP option but what is the difference between all the models?

Hi Hariharan,

The difference between packages can be seen in the package drawings on page 3 as well as the package outline section (towards the end) of the datasheet.

Additional package information including orderable device number, package type, package drawing etc. can be found in the package option addendum.

Even after reading the spec sheet I’m still left scratching my head over what is the difference between the lm35H and lm35AH? And what does NOPB mean?

Hariharan,

The NOPB is a designator for lead free versions of devices.

The difference between LM35H and LM35AH would be the mostly the accuracy spec. LM35AH would have a tighter accuracy which you can see in the datasheet. Sections 6.5 and 6.6 correspond to the LM35AH and Sections 6.7 and 6.8 correspond to LM35H.

Which model of the lm35 would you recommend that has the highest accuracy, price is not the main issue

Hariharan,

Any of the device orderables with the "A" designator will give you the highest accuracy. Other than that I would focus on which package you prefer, but for example, LM35AH or LM35AH/NOPB would be a the highest accuracy for that package.

Tanks for all the help but I have one more question, what is the difference between the lm35AH and lm35CAH

Dear Hariharan -

From the Orderables Table (page 22) in the datasheet http://www.ti.com/lit/ds/symlink/lm35.pdf the difference between the -AH and -CAH parts looks to be the rated operating temperature, where -AH is -55C to +150C and -CAH is -40C to +110C.

Is the lm35CAH water resistant?
