MCP6021/1R/2/3/4
5.0 DESIGN AIDS
Microchip provides the basic design tools needed for
the MCP6021/1R/2/3/4 family of operational amplifiers.
5.1 SPICE Macro Model
The latest SPICE macro model available for the
MCP6021/1R/2/3/4 operational amplifiers is on
Microchip’s web site at www.microchip.com. This
model is intended as an initial design tool that works
well in the operational amplifier’s linear region of oper-
ation at room temperature. There is information on its
capabilities within the macro model file.
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 operational
amplifiers) 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 MPLAB
®
Mindi™ Analog
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 at www.microchip.com/mindi.
This interactive circuit designer and simulator enables
designers to quickly generate circuit diagrams and
simulate circuits. Circuits developed using the MPLAB
Mindi
analog 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 pro-
fessionals efficiently identify Microchip devices that fit a
particular design requirement. Available at no cost from
the Microchip web site 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, purchasing 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 you achieve faster time to market. For a complete
listing of these boards, and their corresponding user’s
guides and technical information, visit the Microchip
web site at www.microchip.com/analogtools.
