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 PTC thermistor.
Choose R1 based on the temperature range and the PTC’s value.
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 10kΩ or less.
A capacitor placed in parallel with the feedback resistor will limit bandwidth, improve stability and help reduce noise.
