(1) “Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur, including inoperability and degradation of device reliability and/or performance. Functional operation of the device and/or non-degradation at the Absolute Maximum Ratings or other conditions beyond those indicated in the Operating Ratings is not implied. Operating Ratings indicate conditions at which the device is functional and the device should not be operated beyond such conditions.

(2) For soldering specifications,see product folder at www.ti.com and http://www.ti.com/lit/SNOA549.

(3) If Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/Distributors for availability and specifications.

(4) The maximum power dissipation must be derated at elevated temperatures and is dictated by T_J(MAX), θ_JA, and the ambient temperature, T_A. The maximum allowable power dissipation P_DMAX = (T_J(MAX) - T_A)/ θ_JA or the number given in Absolute Maximum Ratings, whichever is lower.

(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. Absolute Maximum Ratings indicate junction temperature limits beyond which the device may be permanently degraded, either mechanically or electrically.

(2) 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.

(3) Limits are 100% production tested at 25°C. Limits over the operating temperature range are ensured through correlations using statistical quality control (SQC) method.

(4) Offset voltage temperature drift is determined by dividing the change in V_OS at the temperature extremes by the total temperature change.

(5) The number specified is the average of rising and falling slew rates and measured at 90% to 10%.

(6) This parameter is ensured by design and/or characterization and is not tested in production.

(7) Positive Bias Current corresponds to current flowing into the device. Spec does not include input signal dependent currents on the positive input of approximately Vsense / 5KΩ due to topology feedback action.
