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: As long as output current and junction temperature are kept below
the Absolute Maximum Ratings, no damage to the part will occur.
Note 3: The LT6402 is guaranteed functional over the operating
temperature range of –40°C to 85°C.
Note 4: The LT6402C 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 and 85°C but is not tested or QA sampled
at these temperatures. The LT6402I is guaranteed to meet specifi ed
performance from –40°C to 85°C.
Note 5: Since the LT6402-20 is a feedback amplifi er with low output
impedance, a resistive load is not required when driving an ADC.
Therefore, typical output power is very small. In order to compare the
LT6402-20 with typical g
m
amplifi ers that require 50Ω output loading, the
LT6402-20 output voltage swing driving an ADC is converted to OIP3 and
P1dB as if it were driving a 50Ω load.
