2 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.

10 MCP6XXX Amplifier Evaluation Board 1 User s Guide 1.3 MICROCHIP S WEB-BASED MINDI ANALOG SIMULATOR 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 under Online Simulation Tools or by going directly to the Mindi web site at 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 1 DESCRIPTION The MCP6XXX Amplifier Evaluation Board 1 is designed to support inverting/non-inverting amplifiers, voltage follower, inverting/non-inverting comparators, inverting/non-inverting differentiators. However, at this time, the Mindi Amplifier Designer does not support the non-inverting comparator or the non-inverting differentiator. MCP6XXX Amplifier Evaluation Board 1 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 accommodated; see Section Amplifier Modification: 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 1.

12 MCP6XXX Amplifier Evaluation Board 1 User s Guide The power supply voltage should be in the allowed range for the installed op amps. Any of Microchip s op amps that operate below 5.5V can be used. Moreover, power supply is protected by a zener diode with nominal voltage 6.2V and bypassed by a 1.0 µf capacitor. (See Figure 2-3: Power Supply Block. ) The mid-supply reference consists of a voltage divider and a buffer amplifier. (See Figure 2-4: Mid-Supply Reference Block. ) The resistors and capacitors that are part of an amplifier are placed in pin sockets which are labeled. All of the component labels on board keep consistent with those on schematic generated in the Mindi Amplifier Designer. The op amps are bypassed by capacitors and the single op amp U1 can have either a PDIP-8 or SOIC-8 package. PDIP-8 packages are inserted into the DIP-8 socket to the right of the U1 label SOIC-8 packages can be accommodated; see Section Amplifier Modification: Using 8-Pin SOIC Op Amps The (surface mount) test points for power supply, ground, input signal and output signal allow lab equipment to be connected to the board.

Figure 2-29 shows a SOIC-8 op amp soldered onto the MCP6XXX Amplifier Evaluation Board 1. FIGURE 2-29: Op Amp in SOIC-8 package soldered onto the MCP6XXX Amplifier Evaluation Board 1. Figure 2-30 shows a SOIC-8 op amp and a DIP-8 socket, soldered onto the 8-Pin SOIC/MSOP/TSSOP/DIP Evaluation Board available from Microchip Technology Inc (order # SOIC8EV). The two interconnect strips on the bottom are Samtec part # BBS-14-T-B or equivalent and are soldered into the through holes for the DIP-8 socket. Figure 2-31 shows the SOIC8EV board plugged into the MCP6XXX Amplifier Evaluation Board 1. Note: Insert the interconnect strips into the DIP-8 socket on the MCP6XXX Amplifier Evaluation Board 1. Place the SOIC8EV board on the top of the interconnect strips with the same pin orientation. Now solder the strips to the top board; this procedure ensures correct alignment of the strips. Clip the pins flush with the top surface of the SOIC8EV board, then solder the SOIC-8 op amp on the top. DS51667A-page Microchip Technology Inc.
