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
= +0.5V and +0.5V ≤ V
CM
≤ +4.5V.
Note 4: Tested over the specified input common-mode range.
Note 5: Tested for 0 ≤ V
OUT
≤ V
CC
. Does not include current through external feedback network.
Note 6: Channel-to-channel isolation specification applies to the MAX4242/MAX4243/MAX4244 only.
