Application Information
(Continued)
for offset voltage, CMRR and gain. Low cost and low power
consumption are the main advantages of this two op-amp
circuit.
Higher frequency and larger common-mode range applica-
tions are best facilitated by a three op-amp instrumentation
amplifier.
11.0 Spice Macromodel
A spice macromodel is available for the LMC6484. This
model includes accurate simulation of:
input common-mode voltage range
frequency and transient response
GBW dependence on loading conditions
quiescent and dynamic supply current
output swing dependence on loading conditions
and many more characteristics as listed on the macromodel
disk.
Contact your local National Semiconductor sales office to
obtain an operational amplifier spice model library disk.
Typical Single-Supply Applications
The circuit in Figure 17 use a single supply to half wave rec-
tify a sinusoid centered about ground. R
limits current into
the amplifier caused by the input voltage exceeding the sup-
ply voltage. Full wave rectification is provided by the circuit in
