ELECTRICAL CHARACTERISTICS The denotes the specifications which apply over the temperature range
of – 40
°C < TA < 85°C. VS = ±5V, VCM = 0V, VOUT = 0V, unless otherwise noted. (Note 5)
Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
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 LT1801C/LT1801I and LT1802C/LT1802I are guaranteed
functional over the temperature range of – 40
°C to 85°C.
Note 5: The LT1801C/LT1802C are guaranteed to meet specified
performance from 0
°C to 70°C. The LT1801C/LT1802C are designed,
characterized and expected to meet specified performance from
–40
°C to 85°C but are not tested or QA sampled at these temperatures.
The LT1801I/LT1802I 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 LT1802; between the two amplifiers
on the LT1801.
Note 10: Thermal resistance (
θJA) 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 4 of the SO-8 and MS8, Pin 11 of
the SO-14 or the underside metal of the DD package to a larger metal area
(VS– trace).
