(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 Texas Instruments 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 10mA, then the device will be protected. If the device is

enabled when VDD is greater than 5.5V and less than 6.5V, no damage will occur, although operation 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 LM4906, see Figure 10 for additional information.

(5)

Maximum power dissipation in the device (PDMAX) occurs at an output power level significantly below full output power. PDMAX can be

calculated using Equation 1 shown in the Application Information section. It may also be obtained from the power dissipation graphs.

Human body model, 100pF discharged through a 1.5k

Ω resistor.

Machine Model, 220pF–240pF discharged through all pins.
