Note 2: Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and the test conditions, see the Electrical Characteristics. Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may change when the device is not operated under the listed test conditions. Note 3: All voltages are measured with respect to GND, unless otherwise specified. Note 4: Linearity Error is the variation in DC gain from VIN= 1.0V to 5.0V measured at the points 1.0V, 1.5V, 4.5V, and 5.0V. Note 5: See Section THERMAL CONSIDERATIONS to calculate TAMAX. www.national.com 2 |
