NOTE: Stresses greater than those listed under ABSOLUTE MAXIMUM
RATINGS may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or any other
conditions above those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect reliability.

Notes:
1. Three-point measurement guarantees the error band over the specified temperature range.
2. Optimum performance is obtained at current below 1000µA.
