LT1818/LT1819
ELECTRICAL CHARACTERISTICS Note 5:
With ±5V supplies, slew rate is tested in a closed-loop gain of –1
Note 8:
The LT1818C/LT1818I and LT1819C/LT1819I are guaranteed by measuring the rise time of the output from –2V to 2V with an output functional over the operating temperature range of –40°C to 85°C. step from –3V to 3V. With single 5V supplies, slew rate is tested in a
Note 9:
The LT1818C/LT1819C are guaranteed to meet specifi ed closed-loop gain of –1 by measuring the rise time of the output from 1.5V performance from 0°C to 70°C and is designed, characterized and to 3.5V with an output step from 1V to 4V. Falling edge slew rate is not expected to meet the extended temperature limits, but is not tested production tested, but is designed, characterized and expected to be within at –40°C and 85°C. The LT1818I/LT1819I are guaranteed to meet the 10% of the rising edge slew rate. extended temperature limits.
Note 6:
Full-power bandwidth is calculated from the slew rate:
Note 10:
Thermal resistance (θJA) varies with the amount of PC board FPBW = SR/2πVP metal connected to the package. The specifi ed values are for short
Note 7:
This parameter is not 100% tested. traces connected to the leads. If desired, the thermal resistance can be signifi cantly reduced by connecting the V– pin to a large metal area.
