(1)

All voltages are measured with respect to the GND 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 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.

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

(4)

Limits are guaranteed to Texas Instruments' AOQL (Average Outgoing Quality Level).

(5)

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

(6)

(7)

Shutdown current is measured with components R1 and R2 removed.
