tested or QA sampled at these temperatures. The LT1638I/LT1639I are
guaranteed to meet specifi ed performance from –40°C to 85°C. The
LT1638H/LT1639H are guaranteed to meet specifi ed performance from
–40°C to 125°C.

Note 8:
This specifi cation implies a typical input offset voltage of 2mV at
V
CM
= 44V and a maximum input offset voltage of 5mV at V
CM
= 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 amplifi ers 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 specifi ed
performance from 0°C to 70°C and are designed, characterized and
expected to meet specifi ed performance from –40°C to 85°C but not
