(1) Military RETS 611AMX electrical test specification is available on request. The LM611AMJ/883 can also be procured as a Standard
Military Drawing.
(2) Typical values in standard typeface are for T
J
= 25°C; values in boldface type apply for the full operating temperature range. These
values represent the most likely parametric norm.
(3) All limits are specified at room temperature (standard type face) or at operating temperature extremes (bold face type).
(4) Slew rate is measured with op amp in a voltage follower configuration. For rising slew rate, the input voltage is driven from 5V to 25V,
and the output voltage transition is sampled at 10V and 20V. For falling slew rate, the input voltage is driven from 25V to 5V, and output
voltage transition is sampled at 20V and 10V.
