ppm/°C (Max) (1) Parameters identified with boldface type apply at temperature extremes. All other numbers apply at TA = TJ = 25°C. (2) Production tested. (3) A military RETS electrical specification is available on request. (4) Specified by design. Not production tested. These limits are not used to calculate average outgoing quality levels. (5) The average temperature coefficient is defined as the maximum deviation of reference voltage at all measured temperatures between the operating TMAX and TMIN, divided by TMAX − TMIN. The measured temperatures are −55°C, −40°C, 0°C, 25°C, 70°C, 85°C, 125°C.
