MCP6L1/1R/2/4
5.0 DESIGN AIDS
Microchip provides the basic design aids needed for
the MCP6L1/1R/2/4 family of op amps.
5.1 SPICE Macro Model
The latest SPICE macro model for the MCP6L1/1R/2/4
op amp is available on the Microchip web site at
www.microchip.com. The model was written and tested
in official Orcad (Cadence) owned PSPICE. For 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 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 be ensured to 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 (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 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, purchasing 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:
