• Manufacturer: LINER [Linear Technology]

ELECTRICAL CHARACTERISTICS
LT1469
temperature range, –40°C ≤ T
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 and two 100Ω
series resistors. If the differential input voltage exceeds 0.7V, the input
current should be limited to less than 10mA. Input voltages outside the
supplies will be clamped by ESD protection devices and input currents
should also be limited to less than 10mA.
Note 3: A heat sink may be required to keep the junction temperature
below absolute maximum when the output is shorted indefi nitely.
Note 4: The LT1469C and LT1469I are guaranteed functional over the
operating temperature range of – 40°C to 85°C.

Note 5: The LT1469C is guaranteed to meet specifi ed performance from
0°C to 70°C and is designed, characterized and expected to meet specifi ed
performance from –40°C to 85°C but is not tested or QA sampled at these
temperatures. The LT1469I is guaranteed to meet specifi ed performance
from –40°C to 85°C.
Note 6: Slew rate is measured between ±8V on the output with ±12V
swing for ±15V supplies and ±2V on the output with ±3V swing for ±5V
supplies.
Note 7: Full-power bandwidth is calculated from the slew rate. FPBW =
SR/2πV
Note 8: This parameter is not 100% tested.
Note 9: ΔCMRR and ΔPSRR are defi ned as follows: 1) CMRR and PSRR
are measured in μV/V on each amplifi er; 2) the difference between the two
sides is calculated in μV/V; 3) the result is converted to dB.
