Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 7:
The LT6604C-10 is guaranteed to meet 0°C to 70°C specifi cations may cause permanent damage to the device. Exposure to any Absolute and is designed, characterized and expected to meet the extended Maximum Rating condition for extended periods may affect device temperature limits, but is not tested at –40°C and 85°C. The LT6604I-10 is reliability and lifetime. guaranteed to meet specifi ed performance from –40°C to 85°C.
Note 2:
This is the temperature coeffi cient of the internal feedback
Note 8:
Input pins (+IN, –IN, VOCM and VMID) are protected by steering resistors assuming a temperature independent external resistor (RIN). diodes to either supply. If the inputs should exceed either supply voltage,
Note 3:
The input common mode voltage is the average of the voltages the input current should be limited to less than 10mA. In addition, the applied to the external resistors (R inputs +IN, –IN are protected by a pair of back-to-back diodes. If the IN). Specifi cation guaranteed for RIN ≥ 100Ω. differential input voltage exceeds 1.4V, the input current should be limited to less than 10mA.
Note 4:
Distortion is measured differentially using a differential stimulus. The input common mode voltage, the voltage at V
Note 9:
Channel separation (the inverse of crosstalk) is measured by OCM, and the voltage at V driving a signal into one input, while terminating the other input. Channel MID are equal to one half of the total power supply voltage. separation is the ratio of the resulting output signal at the driven channel
Note 5:
Output common mode voltage is the average of the +OUT and to the output at the channel that is not driven. –OUT voltages. The output common mode voltage is equal to VOCM.
Note 6:
The LT6604C-10 is guaranteed functional over the operating temperature range –40°C to 85°C. 660410fb 4
