The q denotes specifications which apply over the full operating

temperature range.

Note 1: These parametes are guaranteed by design. Thermocouple effects

preclude measurement of these voltage levels during automated testing.

Note 2: 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

VIN = 5V, TA = Operating Temperature Range, unless otherwise noted.

filter at 0.1Hz. The LTC1250 is sample tested for noise; for 100% tested

parts contact LTC Marketing Dept.

Note 3: At T

≤ 0°C these parameters are guaranteed by design and not

tested.
