LT1969
ELECTRICAL CHARACTERISTICS The q denotes specifications which apply over the full operating temp-
erature range, otherwise specifications are at TA = 25°C. VS = ±2.5V, VCM = 0V, nominal mode with a 13k resistor from CTRL1 to V–
and a 49.9k resistor from CTRL2 to V –, pulse power tested unless otherwise noted. (Note 9)

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 absolute maximum.
Note 4: Thermal resistance varies depending upon the amount of PC board
metal attached to the device.
θJA is specified for a 2500mm2 test board
covered with 2 oz copper on both sides.
Note 5: Input offset voltage is exclusive of warm-up drift.
Note 6: Slew rate is measured between
±2V on a ±4V output with ±6V
supplies, and between
±1V on a ±1.5V output with ±2.5V supplies. Falling
slew rate is guaranteed by correlation to rising slew rate.
Note 7: Full power bandwidth is calculated from the slew rate:
FPBW = SR/2
πVP.
Note 8: This parameter is not 100% tested.
Note 9: The LT1969C is guaranteed to meet specified performance from 0
°C
to 70
°C. The LT1969C 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.
Note 10: The LT1969C is guaranteed functional over the operating temperature
range of –40
°C to 85°C.
