Note 1:
Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2:
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 3:
If the total source resistance is less than 10k, no DC errors result
from the input bias currents or the mismatch of the input bias currents or
the mismatch of the resistances connected to –IN and +IN.
Note 4:
The CMRR with a voltage gain, A
V
, larger than 10 is 120dB (typ).
Note 5:
At temperatures above 70
°
C, the common mode rejection ratio
lowers when the common mode input voltage is within 100mV of the
supply rails.
Note 6:
The power supply rejection ratio (PSRR) measurement accuracy
depends on the proximity of the power supply bypass capacitor to the
device under test. Because of this, the PSRR is 100% tested to relaxed
limits at final test. However, their values are guaranteed by design to meet
the data sheet limits.
Note 7:
The LTC6800H is guaranteed functional over the operating
temperature range of –40
°
C to 125
°
C. Specifications over the –40
°
C to
125
°
C range (denoted by
G
) are assured by design and characterization
but are not tested or QA sampled at these temperatures.
