LTC1047
1047fa
Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: Connecting any terminal to voltages greater than V
+
or less than V
–
may cause destructive latch-up. It is recommended that no sources
operating from external supplies be applied prior to power-up of the
LTC1047.
Note 3: These parameters are guaranteed by design. Thermocouple effects
preclude measurements of these voltage levels in high speed automatic
test systems. V
OS
is measured to a limit determined by test equipment
capability.
Note 4: Current Noise is calculated from the formula: I
n
= √2q • I
