Note 1 Absolute Maximum Ratings indicate limits beyond which damage to the device may occur DC and AC electrical specifications do not apply when operating
the device beyond its specified operating conditions
Note 2 Parameters are specified at Va e15V and Vb e b15V Min Va to ground voltage is 5V Min Va to Vb voltage is 5V Boldface numbers apply over full
operating temperature ranges All other numbers apply at TAeTje25 C
Note 3 Typicals are at 25 C and represent most likely parametric norm
Note 4 Guaranteed and 100% production tested
Note 5 Guaranteed (but not 100% production tested) over the operating temperature These limits are not used to calculate outgoing quality levels
Note 6 Settling time for gain change is the switching time for gain change plus settling time (see section on Settling Time)
Note 7 WR minimum high threshold voltage increases to 2 4V under the extreme conditions when all three digital inputs are simultaneously taken from 0V to 5V at
a slew rate of greater than 500V mS
