OVERVOLTAGE PROTECTION
up to 16V, in some applications additional external protection
may be needed. Differential inputs exceeding 16V will be clipped
by the protection circuitry. However, if more than a few milliamps
of current is available from the overload source, the protection
circuitry could be destroyed. For differential sources above
16V, adding series resistance limiting input current to 1mA will
prevent damage. Alternatively, 1N4148 signal diodes connected
anti-parallel across the input pins is usually sufficient. In more
demanding applications where bias current is important, diode
connected JFETs such as 2N4416 will be required. See Q1
and Q2 in Figure 1. In either case the differential input voltage
will be clamped to 0.7V. This is sufficient overdrive to produce
the maximum power bandwidth.
the diodes mentioned above will also afford protection from
excessive common mode voltage. In the case of non-invert-
ing circuits, clamp diodes from each input to each supply will
provide protection. Note that these diodes will have substantial
reverse bias voltage under normal operation and diode leak-
age will produce errors.
devices connected to the power supply rails. Unidirectional
zener diode transient suppressors are recommended. The
zeners clamp transients to voltages within the power supply
rating and also clamp power supply reversals to ground.
Whether the zeners are used or not the system power supply
should be evaluated for transient performance including power-
on overshoot and power-off polarity reversals as well as line
regulation. See Z1 and Z2 in Figure 1.
