(1) Repeatability is the ability to reproduce a reading when the measured temperature is applied consecutively, under the same conditions.
(2) Long term stability is determined using accelerated operational life testing at a junction temperature of 150°C.
(3) Hysteresis is defined as the ability to reproduce a temperature reading as the temperature varies from room → hot →room→cold→room. The temperatures used for this test are -40°C, 25°C, and 150°C.
(4) Quiescent current between conversions
