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 indefinitely.

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 specified performance from

0°C to 70°C and is designed, characterized and expected to meet specified

performance from –40°C to 85°C but is not tested or QA sampled at these

temperatures. The LT1469I is guaranteed to meet specified 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 =

Note 8: This parameter is not 100% tested.

Note 9: ΔCMRR and ΔPSRR are defined as follows: 1) CMRR and PSRR

are measured in μV/V on each amplifier; 2) the difference between the two

sides is calculated in μV/V; 3) the result is converted to dB.
