LT6600-2.5
ELECTRICAL CHARACTERISTICS Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 5:
Output common mode voltage is the average of the voltages at may cause permanent damage to the device. Exposure to any Absolute Pins 4 and 5. The output common mode voltage is equal to the voltage Maximum Rating condition for extended periods may affect device applied to Pin 2. reliability and lifetime.
Note 6:
The LT6600C-2.5 is guaranteed functional over the operating
Note 2:
This is the temperature coeffi cient of the internal feedback temperature range of –40°C to 85°C. resistors assuming a temperature independent external resistor (RIN).
Note 7:
The LT6600C-2.5 is guaranteed to meet specifi ed performance
Note 3:
The input common mode voltage is the average of the voltages from 0°C to 70°C and is designed, characterized and expected to meet applied to the external resistors (RIN). Specifi cation guaranteed for RIN specifi ed performance from –40°C and 85°C, but is not tested or QA ≥ 402Ω. For ±5V supplies, the minimum input common mode voltage is sampled at these temperatures. The LT6600I-2.5 is guaranteed to meet guaranteed by design to reach –5V. specifi ed performance from –40°C to 85°C.
Note 4:
Distortion is measured differentially using a single-ended stimulus.
Note 8:
The inputs are protected by back-to-back diodes. If the differential The input common mode voltage, the voltage at VOCM, and the voltage at input voltage exceeds 1.4V, the input current should be limited to less than VMID are equal to one half of the total power supply voltage. 10mA.
