NTC Thermistor (Chip type):Design Support

STEP 1:Please specify the required conditions.

①A basic constitution of circuit
②Reference voltage
③A range of temperature control and a range of an output voltage
④A target temperature and a target output voltage

STEP 2:We’ll make a table and graphs of the main characteristics value

①An output voltage ( the upper and the lower limit )
②Sensitivity ( mV/°C )
③Accuracy in temperature
④Current of circuit

STEP 3:We’ll change the circuit constant and simulate

①Decide the part number
(1)Ｂ value and its tolerance
(2)Resistance value R25 and its     tolerance
②Simulate the resistance value of the peripheries of a fixed resistor and its tolerance

We propose you the best circuit constant.
