(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 ensure specific performance limits. Electrical Characteristics VDD = 12V 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.  
(3) Typicals are measured at 25°C and represent the parametric norm.  
(4) Limits are specified to AOQL (Average Outgoing Quality Level).  
(5) Datasheet min/max specification limits are specified 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.
