Using the LM7131
LIMITS AND PRECAUTIONS
Supply Voltage
The absolute maximum supply voltage which may be ap-
plied to the LM7131 is 12V. Designers should not design for
more than 10V nominal, and carefully check supply toler-
ances under all conditions so that the voltages do not ex-
ceed the maximum.
Differential Input Voltage
Differential input voltage is the difference in voltage between
the non-inverting (+) input and the inverting input (−) of the
op amp. The absolute maximum differential input voltage is
no power supplied to the op amp. This may not be a problem
±
2V across the inputs. This limit also applies when there is

in most conventional op amp designs, however, designers
should avoid using the LM7131 as comparator or forcing the
inputs to different voltages. In some designs, diode protec-
tion may be needed between the inputs. See Figure 12 .
