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 LTC6416C/LTC6416I is guaranteed functional over the
operating temperature range of –40°C to 85°C.
Note 3: The LTC6416C 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 LT6416I is guaranteed to meet specifi ed
performance from –40°C to 85°C.
Note 4: This parameter is pulse tested.
Note 5: Since the LTC6416 is a voltage-output buffer, a resistive load is not
required when driving an AD converter. Therefore, typical output power is very
small. In order to compare the LTC6416 with amplifi ers that require a 50
output load, the LTC6416 output voltage swing driving a given R
L
is converted
to OIP3 and P1dB as if it were driving a 50 load. Using this modifi ed
convention, 2V
P-P
is by defi nition equal to 10dBm, regardless of actual R
L
.
