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 q 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
