ELECTRICAL CHARACTERISTICS The l denotes the specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C. Unless otherwise specied VS = 5V (V+ = 5V, V– = 0V), RIN = 806Ω, and
RLOAD = 1k.

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 coefcient of the internal feedback
resistors assuming a temperature independent external resistor (RIN).
Note 3: The input common mode voltage is the average of the voltages
applied to the external resistors (RIN). Specication guaranteed for RIN ≥
229Ω.
Note 4: Distortion is measured differentially using a differential stimulus.
The input common mode voltage, the voltage at VOCM, and the voltage at
VMID are equal to one half of the total power supply voltage.
Note 5: Output common mode voltage is the average of the +OUT and
–OUT voltages. The output common mode voltage is equal to VOCM.
Note 6: The LT6604C-5 is guaranteed functional over the operating
temperature range –40°C to 85°C.
Note 7: The LT6604C-5 is guaranteed to meet 0°C to 70°C specications
and is designed, characterized and expected to meet the extended
temperature limits, but is not tested at –40°C to 85°C. The LT6604I-5 is
guaranteed to meet specied performance from –40°C to 85°C.
Note 8: Input pins (+IN, –IN, VOCM and VMID) are protected by steering
diodes to either supply. If the inputs should exceed either supply voltage,
the input current should be limited to less than 10mA. In addition, the
inputs +IN, –IN are protected by a pair of back-to-back diodes. If the
differential input voltage exceeds 1.4V, the input current should be limited
to less than 10mA
Note 9: Channel separation (the inverse of crosstalk) is measured by
driving a signal into one input while terminating the other input. Channel
separation is the ratio of the resulting output signal at the driven channel
to the output at the channel that is not driven.
