DESIGN AIDS

Microchip provides the basic design aids needed for

the MCP651/2/5 family of op amps.

5.1

SPICE Macro Model

The latest SPICE macro model for the MCP651/2/5 op

amps is available on the Microchip web site at

www.microchip.com. This model is intended to be an

initial design tool that works well in the op amp’s linear

region of operation over the temperature range. See

the model file for information on its capabilities.

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 (using

op amps) design. Available at no cost from the Micro-

chip web site at www.microchip.com/filterlab, the Fil-

ter-Lab 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 actual filter perfor-

mance.

5.3

Mindi™ Circuit Designer &

Simulator

Microchip’s Mindi™ Circuit Designer & Simulator aids

in the design of various circuits useful for active filter,

amplifier and power management applications. It is a

free online circuit designer & simulator available from

the Microchip web site at www.microchip.com/mindi.

This interactive circuit designer & simulator enables

designers to quickly generate circuit diagrams, and

simulate circuits. Circuits developed using the Mindi

Circuit Designer & Simulator can be downloaded to a

personal computer or workstation.

5.4

Microchip Advanced Part Selector

(MAPS)

MAPS is a software tool that helps efficiently identify

Microchip devices that fit a particular design require-

ment. Available at no cost from the Microchip website

at www.microchip.com/maps, the MAPS is an overall

selection tool for Microchip’s product portfolio that

includes Analog, Memory, MCUs and DSCs. Using this

tool, a customer 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.

5.5

Analog Demonstration and

Evaluation Boards

Microchip offers a broad spectrum of Analog Demon-

stration and Evaluation Boards that are designed to

help customers achieve faster time to market. For a

complete listing of these boards and their correspond-

ing user’s guides and technical information, visit the

Microchip web site at www.microchip.com/analog

tools.

Some boards that are especially useful are:

• MCP6XXX Amplifier Evaluation Board 1

• MCP6XXX Amplifier Evaluation Board 2

• MCP6XXX Amplifier Evaluation Board 3

• MCP6XXX Amplifier Evaluation Board 4

• Active Filter Demo Board Kit

• 8-Pin SOIC/MSOP/TSSOP/DIP Evaluation Board,
