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: This is the temperature coeffi cient of the internal feedback
resistors assuming a temperature independent external resistor (R
IN
).
Note 3: The input common mode voltage is the average of the voltages
applied to the external resistors (R
IN
). Specifi cation guaranteed for
R
IN
≥ 100.
Note 4: Distortion is measured differentially using a differential stimulus,
The input common mode voltage, the voltage at V
OCM
, and the voltage at
V
MID
are equal to one half of the total power supply voltage.
Note 5: Output common mode voltage is the average of the voltages at
Pins 4 and 5. The output common mode voltage is equal to the voltage
applied to V
OCM
.
Note 6: The LT6600C is guaranteed functional over the operating
temperature range –40°C to 85°C.
Note 7: The LT6600C is guaranteed to meet 0°C to 70°C specifi cations and
is designed, characterized and expected to meet the extended temperature
limits, but is not tested at –40°C and 85°C. The LT6600I is guaranteed to
meet specifi ed performance from –40°C to 85°C.
Note 8: The inputs are protected by back-to-back diodes. If the differential
input voltage exceeds 1.4V, the input current should be limited to less than
10mA.
