LTC1047
ELECTRICAL CHARACTERISTICS The ● denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. VS = ±5V, unless otherwise noted.

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. VOS is measured to a limit determined by test equipment
capability.
Note 4: Current Noise is calculated from the formula: In = √2q • IB) where
q = 1.6 • 10–19 Coulomb.
