Dear,
we have been using the TL598QD for many years and we recognized now that is offered only commercial version with operation temperature 0°C to +70°C .We are able measure are electronics assembled by TL598CD in temperature -40 °C and check the right function our electronics.
I have question.Why did you stop production QD version ? Was it due small demand about this variant ? Can we presume that the production process is still the same from beginning and due this our test in temperature -40°C will be successful ?
Thank you.
Best regards
