Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: A heat sink may be required to keep the junction temperature
below absolute maximum. This depends on the power supply voltage and
how many amplifiers are shorted.
Note 4: Thermal resistance varies depending upon the amount of PC board
2
metal attached to Pin 5 of the device. θ is specified for a 2500mm test
JA
board covered with 2oz copper on both sides.
Note 5: Gain is measured by changing the input voltage, and dividing the
change in output voltage by the change in input voltage.
Note 3: The LT6550C/LT6551C are guaranteed to meet specified
performance from 0°C to 70°C and 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 LT6550I/LT6551I are
guaranteed to meet specified performance from –40°C to 85°C.
Note 6: Minimum supply voltage is guaranteed by the PSRR test.
Note 7: The supply current specification includes additional output current
through the internal feedback and gain resistor.
Note 8: Guaranteed by correlation to slew rate at 5V and ±5V.
Note 9: The inputs are protected from ESD with diodes to the supplies.
Note 10: Noise is input referred, including internal gain resistors.
