USER MANUAL MCP6H04 Microchip
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.

Chapter 2. Installation and Operation
2.1 INTRODUCTION
This chapter describes how to set up the MCP6H04 Evaluation Board. Topics discussed in this chapter include:
- Required Tools
• MCP6H04 Evaluation Board Set-Up
• MCP6H04 Evaluation Board Operation
2.2 REQUIRED TOOLS
The following tools are required for testing the functionality of the board:
- Lab power supply
- Lab dual signal source (e.g., dual function generator)
- Lab measurement equipment (e.g., oscilloscope)
2.3 MCP6H04 EVALUATION BOARD SET-UP
The MCP6H04 Evaluation Board uses a quad op amp in difference amplifier configuration with input buffers and voltage reference. Figure 2-1 shows the circuit diagram of the board.

The power supply voltage needs to be in the allowed range for the op amp. The MCP6H04 device supports a maximum of 16V power supply. The power supply is protected by a Zener diode with a nominal voltage of 16V and bypassed by a 1 F capacitor (see Figure 2-3).
The mid-supply reference voltage consists of a voltage divider and a buffer amplifier (see Figure 2-4).
The resistors that are part of the amplifier are placed in pin sockets, which are labeled. All component labels on board are consistent with those on the schematic. The op amp on board is a 14-lead SOIC package, and is bypassed by a 0.1 F capacitor.
The test points for the power supply, ground, input signals, output signals, and voltage reference allow lab equipment to be connected to the board. The MCP6H04 Evaluation Board top view is shown in Figure 2-2.
