filter at 0.1Hz. Contact LTC factory for sample tested or 100% tested noise
parts.
Note 4: All output swing measurements are taken with the load resistor
connected from output to ground. For single supply tests, only the positive
swing is specified (negative swing will be 0V due to the pull-down effect of
the load resistor). For dual supply operation, both positive and negative
swing are specified.
The
● denotes specifications which apply over the full operating
temperature range.
Note 1: These parameters are guaranteed by design. Thermocouple effects
preclude measurement of these voltage levels during automated testing.
Note 2: At T ≤ 0°C these parameters are guaranteed by design and not
tested.
Note 3: 0.1Hz to 10Hz noise is specified DC coupled in a 10-sec window;
0.1Hz to 1Hz noise is specified in a 100-sec window with an RC highpass
