(6) CMRR definition: [|ÎVOUT/ÎVCM|/AV] with 0.1V differential input voltage. ÎVOUT is the change in output voltage with offset shift
subtracted out.
(7) Positive current correspondes to current flowing in the device.
(8) Drift determined by dividing the change in parameter distribution at temperature extremes by the total temperature change.
(9) +PSRR definition: [|ÎVOUT/ÎV+| /AV], -PSRR definition: [|ÎVOUT/ÎVâ| /AV] with 0.1V differential input voltage. ÎVOUT is the change in
output voltage with offset shift subtracted out.
(10) CMRR definition: [|ÎVOUT/ÎVCM|/AV] with 0.1V differential input voltage. ÎVOUT is the change in output voltage with offset shift
subtracted out.
