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.

(2)

Military/Aerospace specified devices are required, please contact the Texas Instruments Sales Office/ Distributors for availability and

specifications.

(3)

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 the Absolute Maximum Ratings,

whichever is lower. For the LM4861, TJMAX = 150°C, and the typical junction-to-ambient thermal resistance, when board mounted, is

140°C/W.

All voltages are measured with respect to the ground pin, unless otherwise specified.

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

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

(3)

Typicals are measured at 25°C and represent the parametric norm.

(4)

Limits are specified to TI's AOQL (Average Outgoing Quality Level).

(5)

The quiescent power supply current depends on the offset voltage when a practical load is connected to the amplifier.
