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 LTC6400C is guaranteed functional over the operating
temperature range of –40°C to 85°C.
Note 4: The LTC6400C is guaranteed to meet specifi ed performance from
0°C to 70°C. It is designed, characterized and expected to meet specifi ed

performance from –40°C to 85°C but is not tested or QA sampled at these
temperatures. The LTC6400I is guaranteed to meet specifi ed 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. R
Note 7: Since the LTC6400-26 is a feedback amplifi er 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
LTC6400-26 with amplifi ers that require 50Ω output load, the LTC6400-26
output voltage swing driving a given R
if it were driving a 50Ω load. Using this modifi ed convention, 2V
