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
±2V across the inputs. This limit also applies when there is
no power supplied to the op amp. This may not be a problem
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.
