Note the following details of the code protection feature on Microchip devices:
• Microchip products meet the specification contained in their particular Microchip Data Sheet.
• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
• Microchip is willing to work with the customer who is concerned about the integrity of their code.
• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.

1.3 MICROCHIP’S WEB-BASED MINDI™ ANALOG SIMULATOR TOOL
The Mindi™ Analog Simulator tool is an innovative software tool that simplifies analog
circuit design. The Mindi™ Analog Simulator tool supports the following application
circuits: 1) Active Filters, 2) Amplifiers, 3) Battery Chargers, and 4) DC-to-DC
Converters. The Mindi™ Amplifier Designer provides full schematic diagrams of the
amplifier application circuit with recommended component values and displays the
responses in frequency and time domains.
The Mindi™ Analog Simulator tool is a free web-based design tool available on the
Microchip web site at http://www.microchip.com un der “Online Simulat i on Tools” or
by going directly to the Mindi™ web site at http://www.microchip.com/mindi.
The circuit simulator within the Mindi™ Analog Simulator tool can be downloaded and
installed on a personal computer (PC) for more convenient simulations. Modified circuit
files can also be downloaded to the PC.
1.4 MCP6XXX AMPLIFIER EVALUATION BOARD 2 DESCRIPTION
MCP6XXX Amplifier Evaluation Board 2 is designed to support inverting/non-inverting
summing amplifier circuits, however, at this time, the Mindi™ Amplifier Designer only
supports the inverting summing amplifier circuits.
The MCP6XXX Amplifier Evaluation Board 2 has the following features:
• All amplifier resistors and capacitors are socketed
• All of the component labels on board keep consistent with those on schematic
generated in the Mindi™ Amplifier Designer
• Supports all Microchip single op amps
- PDIP-8 package (e.g., MCP6021) are socketed
- SOIC-8 package can be accomodated; see Section 2.4.3 “Amplifier
Modifications Using 8-Pin SOIC Op Amps”
• Test points for connecting lab equipment
• Single supply configuration
Figure 1-2 shows the block diagram of the MCP6XXX Amplifier Evaluation Board 2.
Lab equipment can be attached (via test points) to measure the amplifier response.
