Electrical Characteristics
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: These parameters are guaranteed by design. Thermocouple effects
preclude measurement of these voltage levels in high speed automatic
test systems. VOS 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, AV, 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.
