Notes :
1. F or supply volt ages less than
±15V the absolute maximum input voltage is equal to the supply volt age.
2. T hese specifi cati ons appl y for VCC =
±15V, unless otherwise stated. The offset voltage, offset current and
bi as current specif ic ati ons apply for any supply volt age from a si ngle +5V supply up t o
±15V supplies.
T he off set vol tages and offset current gi ven are the maximum val ues required to drive the output dow n to 1V
or up to +14V wi th a 1mA load current.
T hus, these parameters defi ne an err or band and take in to account the worst case ef fect s of voltage gain
and i nput im pedance.
3. T he response t ime specifi ed i s for a 100mV i nput step w it h 5mV overdr ive.
