A 2 op-amp instrumentation amplifier designed for a gain of 100 is shown in Figure 68. 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.
Higher frequency and larger common-mode range applications are best facilitated by a three op-amp
instrumentation amplifier.

SPICE MACROMODEL
A spice macromodel is available for the LMC6482. 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 Texas Instruments sales office to obtain an operational amplifier spice model library disk.
