Thermal hysteresis

DWeinzie315 on Oct 7, 2025

Category: Hardware

Product Number: LT3042

I have a design using LT3042 4v to 3.3V powering an AD7745. It goes through 20..70C cycles for calibration. Will the LT3042 suffer from thermal hysteresis cycle to cycle?

My feeling is that the LT3042 will have some thermal hysteresis, but the LT3042 will still operate within its specified minimum and maximum limits in the Electrical Characteristics table. In other words, the LT3042 is specified to include the effects of thermal hysteresis.
