Note 1: Absolute Maximum Ratings are those values beyond which the

life of a device may be impaired.

Note 2: The inputs are protected by back-to-back diodes. If the differential

input voltage exceeds 0.7V, the input current should be limited to less than

10mA.

Note 3: A heat sink may be required to keep the junction temperature

below the absolute maximum rating when the output is shorted

indefinitely.

Note 4: The LT1722C/LT1722I, LT1723C/LT1723I, LT1724C/LT1724I

are guaranteed functional over the operating temperature range of

–40

°C to 85°C.

Note 5: The LT1722C/LT1723C/LT1724C are guaranteed to meet specified

performance from 0

°C to 70°C. The LT1722C/LT1723C/LT1724C 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 LT1722I/LT1723I/LT1724I are guaranteed to meet specified

performance from –40

°C to 85°C.

Note 6: Input offset voltage is pulse tested and is exclusive of warm-up

drift.

Note 7: Slew rate is measured between

±2V on the output with ±3V input

for

±5V supplies and ±1V on the output with ±1.5V input for single 5V

supply. (For 5V supply, the voltage levels are 2.5V referred.)

Note 8: Full power bandwidth is calculated from the slew rate:

FPBW = SR/2

Note 9 : This parameter is not 100% tested.

Note 10 : This parameter is guaranteed through correlation with slew rate.
