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 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 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.
