Electrical Table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very limited self-heating of the device such that TJ = TA. No specification of parametric performance is indicated in the electrical tables under conditions of internal self-heating where TJ> TA.
Typical values represent the most likely parametric norm as determined at the time of characterization. Actual typical values may vary over time and will also depend on the application and configuration. The typical values are not tested and are not ensured on shipped production material.
Limits are 100% production tested at 25°C. Limits over the operating temperature range are specified through correlations using statistical quality control (SQC) method.
Number specified is the slower of positive and negative slew rates.
The EMI Rejection Ratio is defined as EMIRR = 20log ( VRF_PEAK/ΔVOS).
The typical value is calculated by applying absolute value transform to the distribution, then taking the statistical average of the resulting distribution.
This parameter is specified by design and/or characterization and is not tested in production.
The specified limits represent the lower of the measured values for each output range condition.
