1049fb
Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
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
LTC1049.

Note 3: These parameters are guaranteed by design. Thermocouple effects
preclude measurement 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
b
)
where q = 1.6 • 10
–19
Coulomb.
