BURR-BROWN

SPICE BASED MACROMODELS, REV. F

By Hubert Biagi, R. Mark Stitt, Bonnie Baker, and Stephan Baier

INTRODUCTION

Computer based simulation has an importance because it can

significantly reduce the development time and therefore

speed up the time-to-market process. The increased use of

SPICE based simulation software has created a rising de-

mand for accurate models. Such models, or macromodels,

should reflect the actual performance of the component, but

without carrying the burden of too many circuit details,

which can lead to convergence problems. BURR-BROWN

has responded to this need and provides macromodels for a

broad range of semiconductor products. This Application

Bulletin, and the accompanying disk is a collection of

SPICE models of BURR-BROWN op amps, difference

amps, instrumentation amps, isolation amps, and analog

function circuits. There are four different levels of model

topologies used, which are:

Level I:

Standard Macromodel

Level II: Enhanced Macromodel

Level III: Multi-Pole/Zero Macromodel

Level IV: Simplified Circuit Model

鈥?The standard op amp macromodels were derived using the

MicroSim Corporation PSpice

廬

Parts鈩?simulation software.

A detailed description on this macromodel type is given in

Section A.

鈥?The second level of macromodel is an enhanced version of

the standard model, which is indicated by the suffix 鈥淓鈥?in

the model鈥檚 name. This model type is included to offer the

circuit designer a model with a higher level of accuracy. See

Section B for details.

鈥?The Multiple-Pole/Zero macromodel uses the same input

stage as the standard or enhanced op amp macromodel, but

has multiple poles and pole/zero pairs in the mid-section.

This model has the designation 鈥淢鈥? and was used for

wide bandwidth op amps and function circuits where this

topology showed an advantage over the standard topology.

For a detailed description see Section C.

鈥?In some instances, a fourth type of model is available,

which are designated by either an 鈥淴鈥? 鈥淴1鈥? or an 鈥淴2鈥?/div>

suffix. The model of this level is not a macromodel, but

rather a simplified circuit model at the transistor level. The

Here, the Standard macromodels (Level I) are found in the

STD_MOD subdirectory. The Enhanced macromodels

(Level II) are found in the ENH_MOD subdirectory. The

Multi-Pole/Zero macromodels (Level III) are found in the

MPZ_MOD subdirectory, and the Simplified circuit models

(Level IV) are found in the CIR_MOD subdirectory. Ex-

amples of model files are shown in Table I. This application

bulletin and the macromodel disk are being revised fre-

quently. To obtain the latest revision please contact your

nearest sales office. Each model net-list starts with a header

containing the part number, revision information, and the

license statement. It should be noted that the disk contains

only the net-lists of the macromodels, and does not provide

the simulation software that allows the user to run the

models. The structure of the net-lists conforms to the stan-

dard SPICE format, which most SPICE based simulators

will accept. Please refer to the individual software manual if

conflicts are encountered. Burr-Brown also welcomes any

comments, which may be sent to the Applications Depart-

ment at the address given above.

DESCRIPTION

OPA603

Standard Op Amp Macromodel

Enhanced Op Amp Macromodel

Multiple Pole/Zero Macromodel

Simplified Circuit Model

simplified circuit models produce the most accurate simula-

tion results, but because of the complexity, require longer

simulation time. See Section D for a detailed discussion on

these models.

For a complete overview of all available macromodels on

the disk see Table XI on the last page.

DISKETTE INFORMATION

The disk has four different subdirectories, in which the

models are organized according to their topology level:

A:\

CIR_MOD

ENH_MOD

MPZ_MOD

STD_MOD
