Using the LTC Op Amp Macromodels &mdash AN48
PDF, 297 Kb, Archivo publicado: nov 8, 1991
LTC's op amp macromodels are described in detail, along with the theory behind each model and complete schematics of each topology. Extended modeling topics are discussed, such as phase/frequency response modifications and asymmetric slew rate for JFET op amp models. LTC's macromodels are optimized for accuracy and fast simulation times. Simulation times can be further reduced by using streamlining techniques found throughout AN48.

Application Note 48

Using the LTC Op Amp Macromodels
Getting the Most from SPICE and the LTC Library
Walt Jung INTRODUCTION This application note is an overview discussion of the
Linear Technology SPICE macromodel library. It assumes
little if any prior knowledge of this software library or its
history. However, it does assume familiarity with both the
analog simulation program SPICE (or one of its many
derivatives), and modern day op amps, including bipolar,
JFET, and MOSFET amplifier technologies.
Some Preliminary SPICE Facts of Life
In the past few years, SPICE simulations have really begun
to capture a high level of attention on the part of analog
circuit designers. Perhaps this is due to more affordable
high performance computers, or perhaps the time for
simulation is now upon us. In any event, the bottom line is
that IC vendors are now making macromodels for op amps
available to their customers.
For the analog circuit designer, there can be no better fate
for simulations, viewing this situation in terms of which
model to use. Designers no longer need worry about
whether the third party supplierвЂ™s model can really cut it. …

Chopper vs Bipolar Op AmpsвЂ”An Unbiased Comparison
Design Note 42
George Erdi Table 1 lists the parameters of importance. In all input
parameters (except noise) the advantage unquestionably goes to the choppers. 5ОјV maximum offset voltage, 0.5ОјV/В°C maximum drift are commonly found

3V Operation of Linear Technology Op Amps &mdash DN56

3V Operation of Linear Technology Op Amps -Design Note 56
George Erdi
The latest trend in digital electronics is the introduction
of numerous ICs operating on regulated 3V or 3.3V
power supplies. This is a logical development to increase
circuit densities and to reduce power dissipation. In addition, many systems are directly powered by two AA
cells or 3V lithium batteries. Clearly, analog ICs which
work on 3V with good dynamic range to complement
these digital circuits are, and will be, in great demand.
Many Linear Technology operational ampliп¬Ѓers work
well on a 3V supply. The purpose of this design note
is to list these devices and their performance when
powered by 3V. The op amps can be divided into two
groups: single and dual supply devices. The single supply
op amps are optimized for, and fully speciп¬Ѓed at, a 5V
positive supply with the negative supply terminal tied
to ground. Input common mode voltage range goes
below ground, and the output swings to within a few
millivolts of ground while sinking current. Members of
the single supply family are the micropower LTВ®1077/
LT1078/LT1079 single, dual and quad op amps with
40ОјA supply current per ampliп¬Ѓer, the LT1178/LT1179 dual and quad with 13ОјA per ampliп¬Ѓer. The LT1006/
LT1013/LT1014 single, dual and quad have faster speed …
