LM234: is there any latest part to replace LM234?

Hi Marcoo,

They use LM234 for remote temperature sensing. The output current of LM234 is directly proportional to absolute temperature in degrees Kelvin. I think the devices you mentioned are not the suitable one. Could you help double check this?

Hi Aki,

Thank you for the explanation. They are using the LM234 as the temperature sensor. In this application the LM234's linear temp co is the benefit. We do not have a direct replacement for this application. They would have to use a remote temperature sensor. I will add the sensor group to this thread.

Hi Aki,

Can you please send schematic of design so I see what temperature sensor best fits the customer application?

Thanks,

Hi David,

Thank you. I will try to get the schematic, but not sure whether they are willing to share. Do you have similar products like LM234(current source) for temp remote sensor? They have evaluated and tested LM234 for a long time, so it is better if we can offer similar solutions.

Marcoo,

Thank you for the information. So you mean we don't have other current source products like LM234? If pin to pin is not necessary?
