Note 2: Offset voltage drift with VOS e 0 at TA e 25§C is valid only when the ratio of IC1 to IC2 is adjusted to give the initial zero offset. This ratio must be held to within 0.003% over the entire temperature range. Measurements taken at a25§C and temperature extremes. Note 3: Logging conformity is measured by computing the best fit to a true exponential and expressing the error as a base-emitter voltage deviation. Note 4: Refer to RETS194X drawing of military LM194H version for specifications. 2
