Using the LM7131
(Continued)
D/A Output Amplifier
The LM7131 can be used as an output amplifier for fast
digital-to-analog converters. When using the LM7131 with
converters with an output voltage range which may exceed
the differential input voltage limit of
±
2V, it may be necessary
to add protection diodes to the inputs. See Figure 15 For
high speed applications, it may be useful to consider low ca-
pacitance schottky diodes. Additional feedback capacitance
may be needed to control ringing due to the additional input
capacitance from the D/A and protection diodes. When used
with current output D/As, the input bias currents may pro-
duce a DC offset in the output. This offset may be canceled
by a resistor between the positive input and ground.
Spice Macromodel
A SPICE macromodel of the LM7131 and many other Na-
tional Semiconductor op amps is available at no charge from
your National Semiconductor representative.
