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 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 under “Online Simulation 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 3 DESCRIPTION
MCP6XXX Amplifier Evaluation Board 3 is intended to support the difference amplifier
circuits which are generated by the Mindi™ Amplifier Designer.
The MCP6XXX Amplifier Evaluation Board 3 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 3.
Lab equipment can be attached (via test points) to measure the amplifier response.
