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 of each op amp are protected by back-to-back diodes
and diodes to each supply. If either input exceeds the supply or the
differential input voltage exceeds 1.4V, the input current should be limited
to less than 25mA.
Note 3: The LT1567C and LT1567I are guaranteed functional over the
operating temperature range –40
°C to 85°C.
Note 4: The LT1567C is guaranteed to meet specified performance from
0
°C to 70°C. The LT1567C is designed, characterized and expected to
meet specified performance from –40
°C to 85°C but not tested or QA
sampled at these temperatures. The LT1567I is guaranteed to meet
specified performance from – 40
°C to 85°C.

Note 6: This parameter is not 100% tested.
Note 7: The input referred voltage noise density of the unity gain inverter
is 5.6nV/
√Hz which includes the noise of the gain setting resistors.
Note 8: For fC = 2MHz, C1 = C2 = 180pF, R1 = R2 = 604, R3 = 316 and
for fC = 5MHz, C1 = C2 = 180pF, R1 = R2 = 232, R1 = 130. BW is the
bandwidth of the noise measurement (Figure 1 circuit).
Note 9: Under direct short circuit conditions, with TA < 25°C the output
current is reduced.
ELECTRICAL CHARACTERISTICS
The
