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

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

Operating Ratings. Specifications are not guaranteed 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 relevant GND pin unless otherwise specified.

(3)

Best operation is achieved by maintaining 3.0V

proper operation.

(4)

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

(5)

Limits are guaranteed to National’s AOQL (Average Outgoing Quality Level).

(6)

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

(7)

This value represents the 0dB output level of the given amplifier for the given analog supply voltage. Gain values given in the

GAINCONFIG register are relative to these full-scale values for each output amplifier.
