tested or QA sampled at these temperatures. The LT1638I/LT1639I are
guaranteed to meet specied performance from –40°C to 85°C. The
LT1638H/LT1639H are guaranteed to meet specied performance from
–40°C to 125°C.
Note 5: VS = 5V limits are guaranteed by correlation to VS = 3V and
VS = ±15V or VS = ±22V tests.
Note 6: VS = 3V limits are guaranteed by correlation to VS = 5V and
VS = ±15V or VS = ±22V tests.
Note 7: Guaranteed by correlation to slew rate at VS = ±15V, and GBW at
VS = 3V and VS = ±15V tests.
Note 8: This specication implies a typical input offset voltage of 2mV at
VCM = 44V and a maximum input offset voltage of 5mV at VCM = 44V.
Note 9: This parameter is not 100% tested.
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: A heat sink may be required to keep the junction temperature
below absolute maximum. This depends on the power supply voltage
and how many ampliers are shorted.
Note 3: The LT1638C/LT1639C and LT1638I/LT1639I are guaranteed
functional over the operating temperature range of –40°C to 85°C The
LT1638H/LT1639H are guaranteed functional over the operating
temperature range of –40°C to 125°C.
Note 4: The LT1638C/LT1639C are guaranteed to meet specied
performance from 0°C to 70°C and are designed, characterized and
expected to meet specied performance from –40°C to 85°C but not
The
l denotes the specications which apply over the full operating temperature range of – 40°C ≤ TA ≤ 125°C, otherwise
specications are at TA = 25°C. VS = ±15V, VCM = 0V, VOUT = 0V, VSHDN = V– unless otherwise specied. (Note 4)
