Note 2: Operating ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. Datasheet min/max specification limits are guaranteed by design, test, or statistical analy sis. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may change when the device is not operated under the list ed test conditions. Note 3: All voltages are measured with respect to GND, unless otherwise specified. Note 4: Calculated value from Voltage Gain test on each channel. Note 5: Linearity Error is the variation in DC gain from V IN = 1.1V to V IN = 3.8V. Note 6: Input from signal generator: t r,t f < 1 ns. LM2426TE www.national.com 2
