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
LTC1052/LTC7652.
Note 3:
These parameters are guaranteed by design. Thermocouple effects
preclude measurement of the voltage levels in high speed automatic
testing. V
OS
is measured to a limit determined by test equipment
capability. Voltages on C
EXTA
and C
EXTB
, A
VOL
, CMRR and PSRR are
measured to insure proper operation of the nulling loop to ensure meeting
the V
OS
and V
OS
drift specifications. See Package-Induced V
OS
in the
Applications Information section.
Note 4:
Output clamp not connected.
Note 5:
Current noise is calculated from the formula: i
n
= (2q I

)
1/2
, where
q = 1.6 • 10

coulomb.
