Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: The inputs are protected by back-to-back diodes. If the differential
input voltage exceeds 0.7V, the input current should be limited to less than
10mA.
Note 3: A heat sink may be required to keep the junction temperature
below absolute maximum.
Note 4: The LT1884C/LT1885C and LT1884I/LT1885I are guaranteed
functional over the operating temperature range of – 40°C to 85°C.
Note 5: The LT1884C/LT1885C are designed, characterized and expected
to meet specified performance from –40°C to 85°C but are not tested or
QA sampled at these temperatures. LT1884I is guaranteed to meet
specified performance from – 40°C to 85°C.
Note 6: This parameter is not 100% tested.
Note 7: Matching parameters are the difference between amplifiers A and
B in the LT1884 and between amplifiers A and D and B and C in the
LT1885.
Note 8: This parameter is the difference between the two noninverting
input bias currents.
Note 9: ∆CMRR and ∆PSRR are defined as follows: CMRR and PSRR are
measured in µV/V on each amplifier. The difference is calculated in µV/V
and then converted to dB.
