DESIGN AIDS

Microchip provides the basic design tools needed for

the MCP6401/1R/1U/2/4 family of op amps.

5.1

SPICE Macro Model

The latest SPICE macro model for the MCP6401/1R/

1U/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 the

other simulators, it may require translation.

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 guaranteed that it will 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

Mindi™ Circuit Designer and

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

Mindi Circuit Designer and Simulator can be down-

loaded 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 Datasheets,

Purchase, and Sampling of Microchip parts.
