MCP660/1/2/3/4/5/9
5.0 DESIGN AIDS
Microchip provides the basic design aids needed for
the MCP660/1/2/3/4/5/9 family of op amps.
5.1 SPICE Macro Model
The latest SPICE macro model for the
MCP660/1/2/3/4/5/9 op amps is available on the Micro-
chip web site at www.microchip.com. This model is
intended to be an initial design tool that works well in
the linear region of operation over the temperature
range of the op amp. 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 soft-
ware 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 Filter-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 performance.
5.3 Microchip Advanced Part Selector
(MAPS)
MAPS is a software tool that helps 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, a filter can be defined to sort features for a
parametric search of device, and export side-by-side
technical comparison reports. Helpful links are also
provided for data sheets, purchase and sampling of
Microchip parts.
5.4 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
