Soldering process must comply with Reflow Temperature Profile specifications. Refer to www.ti.com/packaging.(4)

(1)

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is functional, but do not specified specific performance limits. For specifications and test conditions, see the Electrical

Characteristics. The specifications apply only for the test conditions listed. Some performance characteristics may degrade when the

device is not operated under the listed test conditions.

(2)

When the input voltage (VI) at any pin exceeds power supplies (VI < GND or VI > V), the current at that pin should be limited to 5 mA.

(3)

The human body model is a 100 pF capacitor discharged through a 1.5 k

Ω resistor into each pin. The machine model is a 200 pF

capacitor discharged directly into each pin.

(4)

Reflow temperature profiles are different for lead-free and non-lead-free packages.

The junction to ambient thermal resistance (

θJA) is specified without a heat sink in still air.

(2)

Changes in output due to self heating can be computed by multiplying the internal dissipation by the thermal resistance.

ACCURACY CHARACTERISTICS

These limits do not include DC load regulation. These stated accuracy limits are with reference to the values in Table 1.

Typicals are at TJ = TA = 25°C and represent most likely parametric norm.

(2)

Accuracy is defined as the error between the measured and reference output voltages, tabulated in the Transfer Table at the specified

conditions of supply gain setting, voltage, and temperature (expressed in °C). Accuracy limits include line regulation within the specified

conditions. Accuracy limits do not include load regulation; they assume no DC load.
