LM34 temperature sensor

Can this sensor be used without an ADC using an RCTIME command
somehow? If not, do you recommend an ADC to use?
Thank you for any help.

I imagine you could use the LM34 with RCTIME. I never have but why not? The
output is a reliable 10mV a degree. How accurate do you need to be? I have
used the LM34 with a LTC1298, worked fine.

Hi Scott,
The LM34 is not well suited for use with the RCtime command. The
RCtime command works better with a current source temperature sensor
like the LM334 or the AD592, or with a thermistor.
Analog to digital converters come in many flavors. A good starter
for one channel with scale and offset adjustments is the ADC0831. App
notes are available from Parallax.

probably go that route.
