AC ELECTRICAL CHARACTERISTICS The
l
denotes the specifi cations which apply over the full operating temperature range, otherwise specifi cations 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 defi ned as (IN+ + IN–)/2. VOUTCM is defi ned as (OUT+ + OUT–)/2. VINDIFF is defi ned as (IN+ – IN–). VOUTDIFF is defi ned as (OUT+ – OUT–). See DC test circuit schematic. SYMBOL PARAMETER CONDITIONS MIN TYP MAX UNITS

Note 1:
Stresses beyond those listed under Absolute Maximum Ratings at these temperatures. The LT6416I is guaranteed to meet specifi ed may cause permanent damage to the device. Exposure to any Absolute performance from –40°C to 85°C. Maximum Rating condition for extended periods may affect device
Note 4:
This parameter is pulse tested. reliability and lifetime.
Note 5:
Since the LTC6416 is a voltage-output buffer, a resistive load is not
Note 2:
The LTC6416C/LTC6416I is guaranteed functional over the required when driving an AD converter. Therefore, typical output power is very operating temperature range of –40°C to 85°C. small. In order to compare the LTC6416 with amplifi ers that require a 50Ω
Note 3:
The LTC6416C is guaranteed to meet specifi ed performance from output load, the LTC6416 output voltage swing driving a given RL is converted 0°C to 70°C. It is designed, characterized and expected to meet specifi ed to OIP3 and P1dB as if it were driving a 50Ω load. Using this modifi ed performance from –40°C and 85°C but is not tested or QA sampled convention, 2VP-P is by defi nition equal to 10dBm, regardless of actual RL. 6416f 6
