LM231: LM231N, for -40°C to 125°C

Hi Ken,

Is there a wider operating junction temperature version of LM231N? such as -40°C to 125°C

These are all legacy IC, and we do not have the industrial operating range in these. LM2917 and LM2907 are also V-to-F converters, but they are limited to 85C as well, due to RC time constant conversion topology.

What is your application?
