AC ELECTRICAL CHARACTERISTICS The l denotes the specications which apply over the full operating
temperature range, otherwise specications are at TA = 25°C. V+ = 3.3V and 3.6V unless otherwise noted, GND = 0V, No RLOAD,
CLOAD = 6pF. VCM = 1.25V, CLHI = VCC, CLLO = 0V unless otherwise noted. VINCM is dened as (IN+ + IN)/2. VOUTCM is dened as
(OUT+ + OUT)/2. VINDIFF is dened as (IN+ – IN). VOUTDIFF is dened as (OUT+ – OUT). See DC test circuit schematic.
at these temperatures. The LT6416I is guaranteed to meet specied
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 ampliers that require a 50Ω
output load, the LTC6416 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.
