Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 5:
With INVIN pin driven to ±2V. may cause permanent damage to the device. Exposure to any Absolute
Note 6:
This parameter is not 100% tested. Maximum Rating condition for extended periods may affect device
Note 7:
The input referred voltage noise density of the unity gain inverter reliability and lifetime. is 5.6nV/√Hz which includes the noise of the gain setting resistors.
Note 2:
The inputs of each op amp are protected by back-to-back diodes
Note 8:
For fC = 2MHz, C1 = C2 = 180pF, R1 = R2 = 604Ω, R3 = 316Ω and and diodes to each supply. If either input exceeds the supply or the for fC = 5MHz, C1 = C2 = 180pF, R1 = R2 = 232Ω, R1 = 130Ω. BW is the differential input voltage exceeds 1.4V, the input current should be limited bandwidth of the noise measurement (Figure 1 circuit). to less than 25mA.
Note 9:
Under direct short circuit conditions, with TA < 25°C the output
Note 3:
The LT1567C and LT1567I are guaranteed functional over the current is reduced. 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. 1567fa 3
