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 amplifi ers are shorted.
Note 4: The LT6205C/LT6206C/LT6207C are guaranteed to meet specifi ed
performance from 0°C to 70°C and are designed, characterized and
expected to meet specifi ed 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 specifi ed performance from –40°C to 85°C. The
LT6205H is guaranteed to meet specifi ed performance from –40°C to 125°C.
Note 5: Matching parameters are the difference between the two amplifi ers
A and D and between B and C of the LT6207; between the two amplifi ers 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/2πV
PEAK
.
Note 9: There are reverse biased ESD diodes on all inputs and outputs.
If these pins are forced beyond either supply, unlimited current will fl ow
through these diodes. If the current is transient in nature and limited to
less than 25mA, no damage to the device will occur.
