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
