TYPICAL PERFOR
ELECTRICAL C
Note 1: Absolute Maximum Ratings are those values beyond which
the life of the device may be impaired.
Note 2: Connecting any input terminal to voltages greater than V
less than ground may cause destructive latch-up. It is recommended
that no inputs from sources operating from external supplies be
applied prior to power-up of the LTC1046.
