Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: All specifications are for T_A = 25°C unless otherwise noted.
Note 3: Selected devices with guaranteed maximum temperature
coefficient are available upon request.
For MIL-STD components, please refer to LTC 883C data sheet for test
listing and parameters.
