Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 5:
Input and output baluns used. See Test Circuit A. may cause permanent damage to the device. Exposure to any Absolute
Note 6:
Measured using Test Circuit B. Maximum Rating condition for extended periods may affect device
Note 7:
Since the LTC6400-14 is a feedback amplifi er with low output reliability and lifetime. impedance, a resistive load is not required when driving an AD converter.
Note 2:
Input pins (+IN, –IN) are protected by steering diodes to either Therefore, typical output power is very small. In order to compare the supply. If the inputs go beyond either supply rail, the input current should LTC6400-14 with amplifi ers that require 50Ω output load, the LTC6400-14 be limited to less than 10mA. output voltage swing driving a given RL is converted to OIP3 and P1dB as
Note 3:
The LTC6400C and LTC6400I are guaranteed functional over the if it were driving a 50Ω load. Using this modifi ed convention, 2VP-P is by operating temperature range of –40°C to 85°C. defi nition equal to 10dBm, regardless of actual RL.
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 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. 640014fb 6
