(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 ensure specific performance limits. Electrical Characteristics state DC and AC electrical

specifications under particular test conditions which ensure specific performance limits. This assumes that the device is within the

Operating Ratings. Specifications are not ensured for parameters where no limit is given, however, the typical value is a good indication

of device performance.

If Military/Aerospace specified devices are required, please contact the TI Sales Office/ Distributors for availability and specifications.

(3)

If the product is in shutdown mode and VDD exceeds 6V (to a max of 8V VDD), then most of the excess current will flow through the ESD

protection circuits. If the source impedance limits the current to a max of 10 ma, then the part will be protected. If the part is enabled

when VDD is greater than 5.5V and less than 6.5V, no damage will occur, although operational life will be reduced. Operation above

6.5V with no current limit will result in permanent damage.

(4)

The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX, θJA, and the ambient temperature

TA. The maximum allowable power dissipation is PDMAX = (TJMAX–TA)/θJA or the number given in Absolute Maximum Ratings, whichever

is lower. For the LM4890, see power derating curves for additional information.

(5)

Human body model, 100 pF discharged through a 1.5 k

Ω resistor.

(6)

All bumps have the same thermal resistance and contribute equally when used to lower thermal resistance. All bumps must be

connected to achieve specified thermal resistance.
