Betwixt: Thanks for your reply, Datasheet of MCP9701A page -2 electrical chac and temperature chac says MCp9701A works from -10*c to +125*C, BUt i want to sense the temperature of -30*c
# Page 12, 4.3 Layout considerations has some recommendation, is that enough or we need more filtering to be used to output lines ?
# will sample the ADC pin at every minute, I hope by that time i can get the voltage at the other end.
# Where did you used your 5V supply regulator ? near to MCP9701A IC ? (I need to use regulator IC to regulate it from 12V)
# What kind of wire's you used at Vout ?(Shielded cable or twisted pair cable) ?
Thank you.

THanks FVM, For using pt100 Thermocoupler i think i need to use opamp IC and i am not familier ith those opamps as i am beginer in electronics i am finding dificult to follow that unless someone guides me,
THE IC's like MCP9701, AD22100 has a fixed voltage raise for each *C. and I find it easy, The only thing is I need to design the power supply to regulate it to 5V from 12V. The only problem is my sensing distance is too long to 10MTs.
