ELECTRICAL CHARACTERISTICS The l denotes the specifications which apply over the full operating

temperature range, otherwise specifications are at TA = 25°C.VS = ±5V, VCM = 0V, VOUT = 0V, pulse power tested unless otherwise

specified. (Note 3)

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.

Note 3: The LT1797C is guaranteed to meet 0°C to 70°C specifications and

is designed, characterized and expected to meet the extended temperature

limits, but is not tested at –40°C and 85°C. The LT1797I is guaranteed to

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

Note 4: This parameter is not 100% tested.

Note 5: VS = 3V limit guaranteed by correlation to 5V tests.

Note 6: Full-power bandwidth is calculated from the slew rate:

FPBW = SR/2πVP
