We have problem with TLV2451ID that it will be a offsetshift på 70-80 uV when they have been in cold.
- Are there any effects that can cause permanent change of offset voltage if the device is powered in a temperature -40°C and/ or storage down to -55°C?
- Does temperature dependent parameters have any form of hysteresis that can give permanent changes to the value in room temperature?
- Do you have any studies of drift of devices being subjected to low temperatures either in operation or storage? Can the results be shared?
