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 |
