John, just for everyone's benefit, what have you seen the LM34
do at higher voltages?
(BTW, all that care that must be taken regarding this device's
sensitivity to capacitive loading and the fact that you need
to included a negative supply or other roundabout methods for
reading temperatures below zero has made me try the LM50 if
I need an analog type sensor.)
Or just use a thermistor. They've been good to me, they are cheap, they don't latch up, don't need a black cat to cross the alley from left to right for negative temps, and heck, they don't even require a uC with an ADC on board.
