Note 1:
Stresses beyond those listed under Absolute Maximum Ratings tested or QA sampled at these temperatures. The LT1638I/LT1639I are may cause permanent damage to the device. Exposure to any Absolute guaranteed to meet specifi ed performance from –40°C to 85°C. The Maximum Rating condition for extended periods may affect device LT1638H/LT1639H are guaranteed to meet specifi ed performance from reliability and lifetime. –40°C to 125°C.
Note 2:
A heat sink may be required to keep the junction temperature
Note 5:
VS = 5V limits are guaranteed by correlation to VS = 3V and below absolute maximum. This depends on the power supply voltage VS = ±15V or VS = ±22V tests. and how many amplifi ers are shorted.
Note 6:
VS = 3V limits are guaranteed by correlation to VS = 5V and
Note 3:
The LT1638C/LT1639C and LT1638I/LT1639I are guaranteed VS = ±15V or VS = ±22V tests. functional over the operating temperature range of –40°C to 85°C The
Note 7:
Guaranteed by correlation to slew rate at VS = ±15V, and GBW at LT1638H/LT1639H are guaranteed functional over the operating VS = 3V and VS = ±15V tests. temperature range of –40°C to 125°C.
