• _{Inputs exceeding +30% or –30% of FS will cause erratic performance.}
CAUTION:
ESD (ElectroStatic Discharge) sensitive
device. Permanent damage may occur on
unconnected devices subject to high energy
electrostatic fields. Unused devices must be
stored in conductive foam or shunts.
Personnel should be properly grounded prior
to handling this device. The protective foam
should be discharged to the destination
socket before devices are removed.
SPECIFICATIONS
(Typical @ 25°C with V_CC = +15V, V_EE = 0V, V_LOGIC = +5V unless otherwise noted.)
