摘要： A testing procedure may determine whether a monolithic voltage reference device meets a temperature drift specification. A first non-room temperature output voltage of the monolithic voltage reference device may be measured while the monolithic voltage reference device is at a first non-room temperature which is substantially different than room temperature. First non-room temperature information may be stored in a memory within the monolithic voltage reference device which is a function of the first non-room temperature output voltage. A second non-room temperature output voltage of the monolithic voltage reference device may be measured while the monolithic voltage reference device is at a second non-room temperature which is substantially different than the room temperature and the first non-room temperature. Second non-room temperature information may be stored in the memory without destroying the first non-room temperature information which is a function of the second non-room temperature output voltage. A determination may be made whether the monolithic voltage reference device meets the temperature drift specification based on a computation that is a function of both the first non-room temperature information and the second non-room temperature information.
