Op Amp with Standard SO-8 Pinout and Limiters—A VLA (Voltage Limiting Amplifier) has two inputs
(V
(V
H
and V
L
in
) which limit the output voltage swing.

and pin 8 voltages using R

. Use the values listed in
for the other components.
Note that this board would require modification for a single-supply circuit. In dual-supply applications,
using R
using R
10
instead of R
8
makes V
H
negative, and using R
13
instead of R
11
makes V
L
positive.
