LM335: temperature deviation

Part Number: LM335
Other Parts Discussed in Thread: LM35, TMP235, LM135A, LM135, LM235A


my customer recently evaluated the LM335 for an ongoing project but wasn’t satisfied with the result. The engineer noticed a temperature deviation of approximately 10 °C which is too much for him.

He needs an alternative that has a deviation of maximum 5°C and offers software compatibility with the LM335 (calculation of the temperature with reference to Vout has to be identical to what is done with the LM335).

He looked at the LM35 and said the specs could fit, but the problem is the software compatibility with LM335.

Is there an alternative you can recommend here?
