hello sir,
  i am using lm35dz for temp. mapping but i can not get mv in o/p. so what is the proper circuit to measure it.

With a 5V analogue reference, you should get about two counts (5 / 1024 = 4.88mV / count) per degree on an analogue input pin.
If you need to measure temperature below zero Celsius, you'll need to offset the negative voltages.
