(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.

(2)

All voltages are measured with respect to the ground (GND) pins unless otherwise specified.

(3)

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

(4)

Datasheet min/max specification limits are specified by design, test, or statistical analysis.

(5)

When operating on a power supply voltage of 0.9V, the LM4916 willl not function below 0°C. At a power supply voltage of 1V or greater,

the LM4916 will operate down to -40°C.

(6)

Ripple on power supply line should not exceed 400mVpp.

(7)

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

(8)

Output power is measured at the device terminals.
