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 5). 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 between V
S
and the V
–
rail
doesn
’
t 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.
