AC ELECTRICAL CHARACTERISTICS The l denotes the specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C. V+ = 3V, V– = 0V, SHDN = 2V, +IN is shorted to +TERM, –IN is shorted to
–TERM, VINCM = VBIAS = 1.5V, input source resistance (RS) is 25Ω on each input (50Ω differential), RL = 50Ω from +OUT to –OUT, +IN
and –IN are AC-coupled, unless otherwise noted. VBIAS is dened as the voltage on theVBIAS pin. VOUTCM is dened as
(+OUT + –OUT)/2. VINCM is dened as (+IN + –IN)/2. VINDIFF is dened as (+IN – –IN). VOUTDIFF is dened as (+OUT – –OUT).
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: The LTC6410C-6/LTC6410I-6 is guaranteed functional over the
operating temperature range of –40°C to 85°C.
Note 3: The LTC6410C-6 is guaranteed to meet specied performance
from 0°C to 70°C. It is designed, characterized and expected to meet
specied performance from –40°C and 85°C but is not tested or QA
