This combined with the stated accuracy of the sensor would make the LM34/5 parts a very good deal and easier to use than the Dallas/Maxim parts.
Allow me to disagree. While I use the LM35, TMP36, etc. I would not consider them superior to the 1-Wire temperature devices out there like the DS18B20. Unlike 1-Wire sensors, the LM35 et al produce a analog signal which can easily pick up noise. Additionally, they are very dependent on a stable voltage source. So while they are significantly less expensive than the 1-Wire sensors out there, they come with significant caveats... just scan the boards here for the many HELP! questions relating to LM35's producing erratic readings.
The 1-Wire devices use a digital bus that can be over 100' long, yet suffer no ill effect, and over a hundred 1-wire devices can operate off of one power source. Additionally, 1-wire sensors are available in all sorts of neat packages like waterproof assemblies. The major downsides are the 12-bit resolution (if you need more) and the cost.
Aces in their places and all that. I use the LM35 on PCBs where I can control voltage, minimize noise pickup with careful trace design, etc. while using DS18B20 for off-board applications where noise resistance, convenience, etc. trumps all other considerations. For even better resolution, I skip LM35's and use 2k52 thermistors and a dedicated 16-bit ADC in a bridge circuit to maximize the resolution of the thermistors across the temperature range that is of interest.
