APPLICATION HINTS
Overvoltage Protection
A very convenient form of overvoltage protection consists of
adding two small signal diodes (1N4148, 1N914 type) in
series with the supply pins (see figure 10). This arrangement
effectively blocks the flow of reverse currents. It also floats
the supply pin above or below the normal V+ or V- value. In
this case the overvoltage signal actually becomes the power

supply of the IC. From the point of view of the chip, nothing
has changed, as long as the difference VS - (V-) does not
exceed + 44 V. The addition of these diodes will reduce the
analog signal range to 1 V below V+ and 1 V above V-, but it
preserves the low channel resistance and low leakage
characteristics.
