(1)

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

(2)

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 VDD = 3V 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 specified for parameters where no limit is given, however, the typical value is a good

indication of device performance.

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

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

When driving 4

Ω loads from a 5V supply, the LM4898LD must be mounted to a circuit board with the exposed-DAP area soldered down

to a 1sq. in plane of 1oz. copper.
