(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 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.

(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)

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

(6)

For DSBGA only, shutdown current is measured in a Normal Room Environment. Exposure to direct sunlight will increase ISD by a

maximum of 2µA.

Electrical Characteristics VDD = 2.6V

(1) (2)

The following specifications apply for VDD = 2.6V, AV = 2, and 8Ω load unless otherwise specified. Limits apply for TA = 25°C.
