(1)
Electrical table values apply only for factory testing conditions at the temperature indicated. Factory testing conditions result in very
limited self-heating of the device.
(2)
Typical values represent the parametric norm at the time of characterization.
(3)
The VOS maximum limit indicated does not include effects of lifetime drift, see APPLICATION NOTE.
(4)
Positive current corresponds to current flowing into the device.
(5)
AC Common Mode Signal is a 16 VPP sine-wave (0V to 16V) at the given frequency.
(6)
For VOL, RL is connected to VS and for VOH, RL is connected to GND.
(7)
For this test input is driven from A1 stage.
(8)
Slew rate is the average of the rising and falling slew rates.
