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 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 4: Thermal resistance varies depending upon the amount of PC board

metal attached to Pin 5 of the device.

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 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.
