Schematic Diagram
Application Information
Static Protection
All devices are static protected by the use of input diodes.
However, strong static fields should be avoided, as it is
possible for the strong fields to cause degraded diode
junction characteristics, which may result in increased input
leakage currents.
Latchup Avoidance
Junction-isolated CMOS circuits employ configurations
which produce a parasitic 4-layer (PNPN) structure. The
4-layer structure has characteristics similar to an SCR, and
under certain circumstances may be triggered into a low
impedance state resulting in excessive supply current. To
avoid this condition, no voltage greater than 0.3V beyond the
supply rails may be applied to any pin. In general, the op
amp supplies must be established simultaneously with, or
before any input signals are applied. If this is not possible,
the drive circuits must limit input current flow to 2mA to
prevent latchup.
