Hi .. i have to make a signal conditioning ckt for thermistor... so i want to get voltage output in standard range... as thermistor resistance changes according to temperature...

plz help me.. i am doing an college project.. requirement is to use a Instrumentation amplifier in the ckt.. can anyone give me ckt and details.. with most cost effective and general purpose Instrumentation amplifier IC..


Thanx in advance .. i am waiting..

Instrumentation amplifiers are used to process differential signals. They aren't involved with a basic thermistor circuit. You can build a voltage divider from the thermistor and a fixed resistor. So you get a voltage. Use an OP buffer to get a low output impedance. Everything else depends on your requirements that haven't been told yet.

thanx for reply my output requirement is 0-5 v and i have to use this IA made by 3 uA741 ICs Instrumentation amplifier - Wikipedia, the free encyclopedia
