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 guarantee specific performance limits. For guaranteed specifications and test conditions, see

the LM56 Electrical Characteristics. The guaranteed 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 the power supply (VI < GND or VI > V

+), the current at that pin should be limited to 5 mA.

The 20 mA maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input

current of 5 mA to four.

(3)

The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature),

θJA (junction to ambient thermal resistance) and TA (ambient temperature). The maximum allowable power dissipation at any

temperature is PD = (TJmax–TA)/θJA or the number given in the Absolute Maximum Ratings, whichever is lower. For this device, TJmax =

125°C. For this device the typical thermal resistance (

θJA) of the different package types when board mounted follow:

(4)

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

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

capacitor discharged directly into each pin.
