AC ELECTRICAL CHARACTERISTICS
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: Input pins (+IN, –IN) are protected by steering diodes to either
supply. If the inputs go beyond either supply rail, the input current should
be limited to less than 10mA.
Note 3: The LTC6401C and LTC6401I are guaranteed functional over the
operating temperature range of –40°C to 85°C
Note 4: The LTC6401C 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 to 85°C but is not tested or QA sampled at these
temperatures. The LTC6401I is guaranteed to meet specied performance
from –40°C to 85°C.
Note 5: Input and output baluns used. See Test Circuit A.
Note 6: Measured using Test Circuit B. RL = 87.5Ω per output.
Note 7: Since the LTC6401-26 is a feedback amplier with low output
impedance, a resistive load is not required when driving an AD converter.
Therefore, typical output power is very small. In order to compare the
LTC6401-26 with ampliers that require 50Ω output load, the output
voltage swing driving a given RL is converted to OIP3 and P1dB as if it were
driving a 50Ω load. Using this modied convention, 2VP-P is by denition
equal to 10dBm, regardless of actual RL.
