LT1469-2
ELECTRICAL CHARACTERISTICS Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 5:
The LT1469C-2 is guaranteed to meet specifi ed performance from may cause permanent damage to the device. Exposure to any Absolute 0°C to 70°C and is designed, characterized and expected to meet specifi ed Maximum Rating condition for extended periods may affect device performance from –40°C to 85°C but is not tested or QA sampled at these reliability and lifetime. temperatures. The LT1469I-2 is guaranteed to meet specifi ed performance
Note 2:
The inputs are protected by back-to-back diodes and two 100Ω from –40°C to 85°C. series resistors. If the differential input voltage exceeds 0.7V, the input
Note 6:
Slew rate is measured between ±8V on the output with ±12V current should be limited to less than 10mA. Input voltages outside the swing for ±15V supplies and ±2V on the output with ±3V swing for ±5V supplies will be clamped by ESD protection devices and input currents supplies. Tested in AV = –10 should also be limited to less than 10mA.
Note 7:
Full-power bandwidth is calculated from the slew rate.
Note 3:
A heat sink may be required to keep the junction temperature FPBW = SR/2πVP. below absolute maximum when the output is shorted indefi nitely.
Note 8:
This parameter is not 100% tested.
Note 4:
The LT1469C-2 and LT1469I-2 are guaranteed functional over the
Note 9:
ΔCMRR and ΔPSRR are defi ned as follows: 1) CMRR and PSRR operating temperature range of – 40°C to 85°C. 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.
