ELECTRICAL CHARACTERISTICS

Note 5: With ±5V supplies, slew rate is tested in a closed-loop gain of –1

by measuring the rise time of the output from –2V to 2V with an output

step from –3V to 3V. With single 5V supplies, slew rate is tested in a

closed-loop gain of –1 by measuring the rise time of the output from 1.5V

to 3.5V with an output step from 1V to 4V. Falling edge slew rate is not

production tested, but is designed, characterized and expected to be within

10% of the rising edge slew rate.

Note 6: Full-power bandwidth is calculated from the slew rate:

Note 7: This parameter is not 100% tested.

Note 8: The LT1818C/LT1818I and LT1819C/LT1819I are guaranteed

functional over the operating temperature range of –40°C to 85°C.

Note 9: The LT1818C/LT1819C are guaranteed to meet specified

performance from 0°C to 70°C and is designed, characterized and

expected to meet the extended temperature limits, but is not tested

at –40°C and 85°C. The LT1818I/LT1819I are guaranteed to meet the

extended temperature limits.
