Microchip Technology 

5.0 DESIGN AIDS

Microchip provides the basic design tools needed for

the MCP6141/2/3/4 family of op amps.

5.1 SPICE Macro Model

The latest SPICE macro model for the MCP6141/2/3/4

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

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 actual filter

performance.

5.3 Mindi™ Simulation Tool

Microchip’s Mindi™ simulation tool aids in the design of

various circuits useful for active filter, amplifier and

power-management applications. It is a free online

simulation tool available from the Microchip web site at

www.microchip.com/mindi. This interactive simulator

enables designers to quickly generate circuit diagrams,

simulate circuits. Circuits developed using the Mindi

simulation tool 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 Microchip devices that

fit a particular design requirement. 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 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.
