Having an accurate and stable reference output voltage across temperature is essential in a wide variety of applications such as data acquisition systems, sensor, and hand-held applications. An important parameter to consider when selecting a reference voltage device is the output voltage temperature coefficient. In this video, the TS6001A evaluation board and a Type K thermocouple are used to determine the temperature coefficient of the TS6001A 2.5V reference voltage device — the industry’s only 2.5V reference voltage that guarantees less than 10ppm/ºC output voltage drift in a SOT23 package. With a current consumption of only 31µA and an initial output voltage accuracy of less than ±0.08%, the TS6001A is an ideal low power solution where output voltage accuracy and stability are important.
