(1)

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 guarantee of parametric performance is indicated in the electrical tables under

conditions of internal self-heating where TJ > TA.

(2)

Limits are 100% production tested at 25°C. Limits over the operating temperature range are guaranteed through correlations using

statistical quality control (SQC) method.

(3)

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 guaranteed on

shipped production material.

(4)

The typical value is calculated by applying absolute value transform to the distribution, then taking the statistical average of the resulting

distribution

(5)

This parameter is guaranteed by design and/or characterization and is not tested in production.

(6)

The EMI Rejection Ratio is defined as EMIRR = 20log ( VRF_PEAK/ΔVOS).

(7)

The specified limits represent the lower of the measured values for each output range condition.
