LT1789-1/LT1789-10
ELECTRICAL CHARACTERISTICS The
l
denotes the specifications which apply over the temperature range of –40°C ≤ TA ≤ 85°C. VS = ±15V, RL = 20k, VCM = VREF = 0V, unless otherwise noted. (Note 4) LT1789-1 LT1789-10 SYMBOL PARAMETER CONDITIONS MIN TYP MAX MIN TYP MAX UNITS

Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 5:
Hysteresis in offset voltage is created by package stress that may cause permanent damage to the device. Exposure to any Absolute differs depending on whether the IC was previously at a higher or lower Maximum Rating condition for extended periods may affect device temperature. Offset voltage hysteresis is always measured at 25°C, but reliability and lifetime. the IC is cycled to 85°C I-grade (or 70°C C-grade) or – 40°C I-grade
Note 2:
Does not include the effect of the external gain resistor R (0°C C-grade) before successive measurement. 60% of the parts will G.
Note 3:
This parameter is not 100% tested. pass the typical limit on the data sheet.
Note 4:
The LT1789C-1/ LT1789C-10 is guaranteed to meet specified
Note 6:
VS = 5V limits are guaranteed by correlation to VS = 3V and performance from 0°C to 70°C and is designed, characterized and VS = ±15V tests. expected to meet these extended temperature limits, but is not tested at
Note 7:
VS = 3V limits are guaranteed by correlation to VS = 5V and –40°C and 85°C. The LT1789I-1/ LT1789I-10 is guaranteed to meet the VS = ±15V tests. extended temperature limits.
Note 8:
This parameter is not tested at VS = 3V on the LT1789-10 due to an increase in sensitivity to test system noise. Actual performance is expected to be similar to performance at VS = 5V.
