Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: The LT1618 is guaranteed to meet performance specifications

from 0°C to 70°C. Specifications over the – 40°C to 85°C operating

temperature range are assured by design, characterization, and correlation

with statistical process controls.

Note 3: Bias currents flow into the ISP and ISN pins.

guaranteed by design and/or correlation to static test.
