LT1722/LT1723/LT1724
ELECTRICAL CHARACTERISTICS The q denotes the specifications which apply over the temperature range of
– 40°C ≤ TA ≤ 85°C. VS = 5V, VCM = 2.5V, RL to 2.5V, unless otherwise noted. (Note 5)

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/2πVP
Note 9 : This parameter is not 100% tested.
Note 10 : This parameter is guaranteed through correlation with slew rate.
