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

specifications under particular test conditions which specify 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.

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 specify specific performance limits. Electrical Characteristics state DC and AC electrical

specifications under particular test conditions which specify 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.

(3)

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

(4)

Limits are ensured to AOQL (Average Outgoing Quality Level).

(5)

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

(6)

Shutdown current is measured in a normal room environment. The Shutdown pin should be driven as close as possible to GND for

minimum shutdown current.
