(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 T
J
= T
A
. No specification of parametric performance is indicated in the electrical tables under
conditions of internal self-heating where T
J
> T
A
.
(2) Limits are 100% production tested at 25°C. Limits over the operating temperature range are specified 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 ensured 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 specified by design and/or characterization and is not tested in production.
(6) The EMI Rejection Ratio is defined as EMIRR = 20log ( V
RF_PEAK
/ΔV
OS
).
