Application Information
A 2 op-amp instrumentation amplifier designed for a gain of
100 is shown in Figure 16. Low sensitivity trimming is made
for offset voltage, CMRR and gain. Low cost and low power
consumption are the main advantages of this two op-amp
circuit.
11.0 SPICE MACROMODEL
A spice macromodel is available for the LMC6482. This
model includes accurate simulation of:
and many more characteristics as listed on the macromodel
disk.
