LT1800IS8-TRPBF

80MHz, 25V/µs Low Power Rail-to-Rail Input and Output Precision Op Amp

Linear Technology 

ELECTRICAL CHARACTERISTICS

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: The inputs are protected by back-to-back diodes and by ESD

diodes to the supply rails. If the differential input voltage exceeds 1.4V or

either input goes outside the rails, the input current should be limited to

less than 10mA.

Note 3: A heat sink may be required to keep the junction temperature

below the absolute maximum rating when the output is shorted

indefinitely.

LT1800

Note 4: The LT1800C/LT1800I are guaranteed functional over the

temperature range of –40°C to 85°C.

Note 5: The LT1800C is guaranteed to meet specified performance from

0°C to 70°C. The LT1800C 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 LT1800I is guaranteed to meet

specified performance from –40°C to 85°C.

Note 6: Minimum supply voltage is guaranteed by power supply rejection

ratio test.

Note 7: Output voltage swings are measured between the output and

power supply rails.

Note 8: This parameter is not 100% tested.
