flects the current industry practice, a better solution
is shown in figure 5. Like figure 4, this circuit uses a
diode bridge (composed of very fast 1N5818s), but in
this case, the diodes are connected directly to the
DIP and 16-pin SOIC packages. The package dimen-

keep the inputs inside the common mode range, it
has the advantage of working even when the power is
off. For further insights in to this subject, see The 48
