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 specification 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 10: The

θJA specified for the DD package is with minimal PCB heat

spreading metal. Using expanded metal area on all layers of a board

reduces this value.

The

● denotes the specifications which apply over the full operating temperature range of –40

°C ≤ TA ≤ 125°C, otherwise

specifications are at TA = 25

°C. VS = ±15V, VCM = 0V, VOUT = 0V, VSHDN = V– unless otherwise specified. (Note 4)

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 amplifiers 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 specified

performance from 0

°C to 70°C and are designed, characterized and

expected to meet specified performance from –40

°C to 85°C but not

tested or QA sampled at these temperatures. The LT1638I/LT1639I are

guaranteed to meet specified performance from –40

°C to 85°C. The

LT1638H/LT1639H are guaranteed to meet specified performance from

–40

°C to 125°C.
