MCP6H91_12 Datasheet, PDF (21/42 Pages) Microchip Technology – 10 MHz, 12V Op Amps

5.0 DESIGN AIDS
Microchip Technology Inc. provides the basic design
tools needed for the MCP6H91/2/4 family of op amps.
5.1 SPICE Macro Model
The latest SPICE macro model for the MCP6H91/2/4
op amp is available on the Microchip web site at
www.microchip.com. The model was written and tested
in PSpice, owned by Orcad (Cadence^®). 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 the specification range listed in the op
amp data sheet. The model behaviors under these
conditions cannot be guaranteed 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
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 MAPS (Microchip Advanced Part
Selector)
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 web site at www.microchip.com/
maps, 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, purchases and
sampling of Microchip parts.
