• Manufacturer Part Number: spx385am1-l-2-5-tr
• Description: 2.5 -micropower Voltage Reference
• Manufacturer: Exar Corporation

Stresses greater than those listed under ABSOLUTE MAXIMUM RAT-
INGS 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 conditions for extended
periods may affect reliability.
ABSOLUTE MAXIMUM RATINGS
