The

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

°C ≤ TA ≤ 125°C for LT1637H and

–55

°C ≤ TA ≤ 125°C for LT1637MP. 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. 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.

Note 3: The LT1637C and LT1637I are guaranteed functional over the

operating temperature range of – 40

°C to 85°C. The LT1637H is guaranteed

functional over the operating temperature range of –40

°C to 125°C. The

LT1637MP is guaranteed functional over the operating temperature range

–55

°C to 125°C.

Note 4: The LT1637C is guaranteed to meet specified performance from

0

°C to 70°C. The LT1637C is designed, characterized and expected to meet

specified performance from – 40

°C to 85°C but is not tested or QA

sampled at these temperatures. The LT1637I is guaranteed to meet

specified performance from – 40

°C to 85°C. The LT1637H is guaranteed to

meet specified performance from –40

°C to 125°C and the LT1637MP is

guaranteed to meet specified performance from –55

°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 specification implies a typical input offset voltage of 650

µV at

VCM = 44V and a maximum input offset voltage of 5.4mV at VCM = 44V.

Note 9: This parameter is not 100% tested.
