Use the op amp in a linear
operating region. Linear output swing is usually specified under the
AOL test conditions. TLV9002 linear output swing 0.05 V to 3.25
V.
The connection, Vin, is a positive
temperature coefficient output voltage. To correct a negative temperature
coefficient (NTC) output voltage, switch the position of R1 and the
NTC thermistor.
Choose R1 based on the
temperature range and the value of NTC.
Using high value resistors can
degrade the phase margin of the amplifier and introduce additional noise in the
circuit. It is recommended to use resistor values around 10 kΩ or less.
A capacitor placed in parallel
with the feedback resistor will limit bandwidth, improve stability and help
reduce noise.
