Note 1: The MAX4240EUK, MAX4241EUA, MAX4242EUA, and MAX4243EUB specifications are 100% tested at T
A
= +25°C. All
temperature limits are guaranteed by design.
Note 2: Shutdown mode applies to the MAX4241/MAX4243 only.
Note 3: Input bias current and input offset current are tested with V
CC
= +5.0V and 0 ≤ V
CM
≤ 5.0V.
Note 4: Tested over the specified input common-mode range.
Note 5: Tested for 0 ≤ V
