Factory testing conditions result in very limited self-heating of the device such that TJ = TA. No ensured specification of parametric performance is indicated in the electrical tables under conditions of internal self-heating where TJ > TA. Absolute Maximum Ratings indicate junction temperature limits beyond which the device may be permanently degraded, either mechanically or electrically. (2) All limits are specified by testing, statistical analysis or design. (3) Typical values represent the most likely parametric norm 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 short circuit test is a momentary open loop test. 1.8V AC Electrical Characteristics (1) Unless otherwise is specified, all limits ensured for TA = 25°C, V + = 1.8V, V− = 0V, V CM = VO = V +/2, and R L > 1 MΩ. Boldface limits apply at the temperature extremes.
