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 inputs are protected by back-to-back diodes. If the differential
input voltage exceeds 1.4V, the input current should be limited to less than
10mA.
Note 3: A heat sink may be required to keep the junction temperature below
the absolute maximum rating when the output is shorted indefinitely.
Note 4: The LT6220C/LT6221C/LT6222C and LT6220I/LT6221I/LT6222I
are guaranteed functional over the temperature range of –40°C and 85°C.
Note 5: The LT6220C/LT6221C/LT6222C are guaranteed to meet specified
performance from 0°C to 70°C. The LT6220C/LT6221C/LT6222C are
designed, characterized and expected to meet specified performance from
–40°C to 85°C but is not tested or QA sampled at these temperatures. The
LT6220I/LT6221I/LT6222I are guaranteed to meet specified performance
from –40°C to 85°C.
Note 6: Minimum supply voltage is guaranteed by power supply rejection
ratio test.
Note 7: Output voltage swings are measured between
the output and
power supply rails.
Note 8:
This parameter is not 100% tested.
Note 9: Matching parameters are the difference between amplifiers A and
D and between B and C on the LT6222; between the two amplifiers on the
LT6221.
Note 10: Thermal resistance (θ
JA
) varies with the amount of PC board
metal connected to the package. The specified values are for short
traces connected to the leads. If desired, the thermal resistance can be
substantially reduced by connecting Pin 2 of the LT6220CS5/LT6220IS5 or
the underside metal of DD packages to a larger metal area (V
S
–
trace).
