DESIGN AIDS

Microchip provides the basic design tools needed for

the MCP6441 op amp.

5.1

SPICE Macro Model

The latest SPICE macro model for the MCP6441 op

amp is available on the Microchip web site at

www.microchip.com. The model was written and tested

in the official OrCAD (Cadence®) owned PSpice®. For

the other simulators, translation may be required.

The model covers a wide aspect of the op amp's

electrical specifications. Not only does the model cover

voltage, current and resistance of the op amp, but it

also covers the temperature and the noise effects on

the behavior of the op amp. The model has not been

verified outside of the specification range listed in the

op amp data sheet. The model behaviors under these

conditions cannot ensure it will match the actual op

amp performance.

Moreover, the model is intended to be an initial design

tool. Bench testing is a very important part of any

design and cannot be replaced with simulations. Also,

simulation results using this macro model need to be

validated by comparing them to the data sheet

specifications and characteristic curves.

5.2

FilterLab® Software

Microchip’s FilterLab software is an innovative software

tool that simplifies analog active filter design using op

amps. Available at no cost from the Microchip web site

at www.microchip.com/filterlab, the FilterLab design

tool provides full schematic diagrams of the filter circuit

with component values. It also outputs the filter circuit

in SPICE format, which can be used with the macro

model to simulate the actual filter performance.

5.3

Mindi™ Circuit Designer and

Simulator

Microchip’s Mindi Circuit Designer and Simulator aids

in the design of various circuits useful for active filter,

amplifier and power-management applications. It is a

free online circuit designer and simulator, available

from

the

Microchip

web

site

www.micro-

chip.com/mindi. This interactive circuit designer and

simulator enables designers to quickly generate circuit

diagrams and simulate circuits. Circuits developed

using the Mindi Circuit Designer and Simulator can be

downloaded to a personal computer or workstation.

5.4

Microchip Advanced Part Selector

(MAPS)

MAPS is a software tool that helps semiconductor

professionals efficiently identify the Microchip devices

that fit a particular design requirement. Available at no

cost from the Microchip website at www.micro-

chip.com/ maps, the MAPS is an overall selection tool

for Microchip’s product portfolio that includes Analog,

Memory, MCUs and DSCs. Using this tool, you can

define a filter to sort features for a parametric search of

devices and export side-by-side technical comparison

reports. Helpful links are also provided for Data Sheets,

Purchase and Sampling of Microchip parts.
