Note 1: Stresses beyond those listed under Absolute Maximum Ratings
may cause permanent damage to the device. Exposure to any Absolute
Maximum Rating condition for extended periods may affect device
reliability and lifetime.
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/2πVP
Note 9 : This parameter is not 100% tested.
Note 10 : This parameter is guaranteed through correlation with slew rate.
