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: The inputs are protected by back-to-back diodes. If the differential
input voltage exceeds 1.4V, 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. This depends on the power supply voltage and
how many ampliers are shorted.
Note 4: The LT6205C/LT6206C/LT6207C are guaranteed to meet specied
performance from 0°C to 70°C and are designed, characterized and
expected to meet specied performance from –40°C to 85°C but are not
tested or QA sampled at these temperatures. The LT6205I/LT6206I/LT6207I
are guaranteed to meet specied performance from –40°C to 85°C. The
LT6205H is guaranteed to meet specied performance from –40°C to 125°C.
Note 5: Matching parameters are the difference between the two ampliers
A and D and between B and C of the LT6207; between the two ampliers of
the LT6206.
Note 6: This parameter is not 100% tested.
Note 7: Output voltage swings are measured between the output and
power supply rails.
Note 8: Full power bandwidth is calculated from the slew rate
measurement: FPBW = SR/2πVPEAK.
Note 9: There are reverse biased ESD diodes on all inputs and outputs.
If these pins are forced beyond either supply, unlimited current will ow
through these diodes. If the current is transient in nature and limited to
less than 25mA, no damage to the device will occur.
