TABLE IV. Macromodel Component Prefix Definitions.
LIMITATIONS
These macromodels are intended to help designers simulate
typical amplifier performance. The macromodels were com-
piled using data sheet typical specifications. Where data
sheet specifications were not available, typical measured
values or design values were used. Macromodels were
verified with several standard simulations such as gain-
phase and large- and small-signal transient response. In
some cases, adjustments were made to the macromodels so
simulations with the macromodel more closely agreed with
actual measured typical performance.
Since these macromodels only simulate the typical perfor-
mance of certain selected specifications, they will not pre-
dict actual device performance under all conditions. Good
design practice dictates that, in addition to simulation with
macromodels, circuit verification must include:
1) worst case analysis with data sheet minimum and maxi-
mum room temperature specifications
2) worst case analysis with variation of specifications over
the operating temperature range
3) thorough breadboard evaluation
4) complete prototype characterization
DUAL AND QUAD OP AMPS
All op amps are modeled as single devices. To model duals
or quads, use two or four models. Quiescent current for the
dual or quad op amp macromodel is the dual or quad op amp
quiescent current divided by two or four.
INSTRUMENTATION AMPLIFIERS
AND DIFFERENCE AMPLIFIERS
Instrumentation amplifier and difference amplifier
macromodels use standard op amp macromodels plus addi-
tional components as shown in Figures 1 and 2. There are
two types of models used for difference amplifiers. They are
the four-resistor difference amplifier and the five-resistor
difference amplifier.
FOUR-RESISTOR DIFFERENCE AMPLIFIER
The four-resistor difference amplifier macromodel, used for
the INA105, INA106, and the difference amplifier section in
all instrumentation amplifier macromodels, is shown in
