Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: These parameters are guaranteed by design. Thermocouple effects
preclude measurement of these voltage levels during automated testing.
Note 3: 0.1Hz to 10Hz noise is specified DC coupled in a 10s window;
0.1Hz to 1Hz noise is specified in a 100s window with an RC high-pass
filter at 0.1Hz. The LTC1250 is sample tested for noise; for 100% tested
parts contact LTC Marketing Dept.
Note 4: At T ≤ 0°C these parameters are guaranteed by design and not
tested.
