(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) When the input voltage (VI) at any pin exceeds power supplies (VI < GND or VI > VDD), the current at that pin must be limited to 5 mA.
(3) For soldering specifications, see Absolute Maximum Ratings for Soldering.

(1) Limits are specified to TI's AOQL (Average Outgoing Quality Level).
(2) Typical values apply for TJ = TA = 25°C and represent most likely parametric norm.
(3) The 1-µA limit is based on a testing limitation and does not reflect the actual performance of the part. Expect to see a doubling of the current for every 15°C increase in temperature. For example, the 1-nA typical current at 25°C would increase to 16 nA at 85°C.
(4) Source currents are flowing out of the LM26LV or LM26LV-Q1. Sink currents are flowing into the LM26LV or LM26LV-Q1.
(5) Line regulation (DC) is calculated by subtracting the output voltage at the highest supply voltage from the output voltage at the lowest supply voltage. The typical DC line regulation specification does not include the output voltage shift discussed in Voltage Shift.

(1) Limits are specified to TI's AOQL (Average Outgoing Quality Level).
(2) Accuracy is defined as the error between the measured and reference output voltages, tabulated in Table 1 at the specified conditions of supply gain setting, voltage, and temperature (°C). Accuracy limits include line regulation within the specified conditions. Accuracy limits do not include load regulation; they assume no DC load.
(3) Changes in output due to self heating can be computed by multiplying the internal dissipation by the temperature thermal resistance.
