(1) Test levels: (A) 100% tested at +25°C. Over temperature limits set by characterization and simulation. (B) Limits set by characterization
and simulation. (C) Typical value; only for information.
(2) Junction temperature = ambient for +25°C tested specifications.
(3) Junction temperature = ambient at low temperature limit; junction temperature = ambient +30°C at high temperature limit for over
temperature specifications.
(4) Total output offset is: (Output Offset Voltage ± Input Offset Voltage x Gain).
(5) Maximum input at minimum gain for < 1dB gain compression.
