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: Inputs are protected by back-to-back diodes. If the differential
input voltage exceeds 0.7V, the input current must be limited to less than
40mA.
Note 3: A heat sink may be required to keep the junction temperature
below the absolute maximum rating when the output is shorted
indefinitely.
Note 4: The LT6233C/LT6233I the LT6234C/LT6234I, and LT6235C/LT6235I
are guaranteed functional over the temperature range of –40°C to 85°C.
Note 5: The LT6233C/LT6234C/LT6235C are guaranteed to meet specified
performance from 0°C to 70°C. The LT6233C/LT6234C/LT6235C 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.
The LT6233I/LT6234I/LT6235I are guaranteed to meet specied
performance from –40°C to 85°C.
Note 6: Matching parameters are the difference between the two amplifiers
A and D and between B and C of the LT6235; between the two amplifiers
of the LT6234. CMRR and PSRR match are defined as follows: CMRR and
PSRR are measured in µV/V on the matched amplifiers. The difference is
calculated between the matching sides in µV/V. The result is converted to
dB.
