MCP4725 SOT-23-6 EVALUATION BOARD USER’S GUIDE Chapter 1. Quick Start Instructions 1.1 INTRODUCTION The following sections provide an overview of the MCP4725 SOT-23-6 Evaluation Board and Instruction how to program the DAC register and EEPROM of the MCP4725 device using the PICkit Serial Analyzer. The following sections cover the following topics: • What is the MCP4725 SOT-23-6 Evaluation Board? • How to use the MCP4725 SOT-23-6 Evaluation Board with the PICkit Serial Analyzer 1.2 WHAT IS THE MCP4725 SOT-23-6 EVALUATION KIT The MCP4725 SOT-23-6 Evaluation Board contains the MCP4725 single channel 12-Bit Digital-to-Analog Converter (DAC) and I2C loading resistors. The purpose of this board is: • Quick evaluation of the MCP4725 features using the PICkit Serial Analyzer: The user can program the DAC Register or EEPROM using the PICkit Serial Analyzer and measure the MCP4725 device analog output voltage using a voltmeter • Easy handling of the MCP4725 device in a tiny SOT23-6 package: The MCP4725 device is available in a small SOT-23-6 package. This board makes it easy to handle the small package device for user’s application evaluations. The user can simply connect the J1 pins on the evaluation board to the user’s test board for a quick evaluation of the MCP4725 device. The MCP4725 supports standard mode (100 kHz), fast mode (400 kHz), and high speed mode (3.4 MHz). This evaluation board is using 5 kΩ for the I2C pull-up resistors. This 5 kΩ supports up to 400 kHz. The user can replace the R1 and R3 with lower values (less than 1 kΩ) for the high-speed mode (3.4 MHz) 1.3 GETTING STARTED WITH PICKIT SERIAL ANALYZER The user can use the MCP4725 SOT-23-6 Evaluation Board in two different ways: (a) together with the PICkit Serial Analyzer or (b) by connecting this board to the user’s target board directly. Figure 1-1 shows the MCP4725 SOT-23-6 Evaluation Board. The SCL, SDA, VDD, and VSS pins in the J1 connector are connected to the MCP4725 device. The MCP4725 SOT-23-6 Evaluation Kit contains two MCP4725 SOT-23-6 Evaluation Boards. This board can easily be programmed using the PICkit Serial Analyzer (DV164122). It is highly recommended that the user order the MCP4725 SOT-23-6 Evaluation Board and the PICkit Serial Analyzer at the same time. On the MCP4725 SOT-23-6 Evaluation Board, the R1 and R3 are the I2C pull-up load resistors for the SDA and SCL, respectively. The user can replace them with their own component values of interest. It is also recommended that these pull-up resistors be removed if the user’s test board has the pull-up resistors already. The MCP4725 SOT-23-6 Evaluation Board also has footprints for additional pull-up resistors (in parallel with the R1 and R3) and loading capacitors. The user can populate the board with their own components. © 2007 Microchip Technology Inc.

Quick Start Instructions 1.3.1 Getting Started with PICkit Serial Analyzer This section describes how to evaluate the MCP4725 device using the PICkit Serial Analyzer. 1.3.1.1 HARDWARE SET-UP 1. Connect the MCP4725 SOT-23-6 Evaluation Board and the PICkit Serial Analyzer together using the J1 connector. 2. Connect a USB cable between the PICkit Serial Analyzer and a Personal Computer. 3. Connect a Digital Voltmeter to VOUT and GND terminals on the MCP4725 SOT-23-6 Evaluation Board. Figure 1-2 shows the connection example. MCP4725 SOT-23-6 Evaluation Board PICkit Serial Analyzer Analog Output Voltage (VOUT) Connected to Voltmeter USB Cable: Connected between the PicKit Serial analyzer and Personal Computer.

DS51669A-page 7 MCP4725 SOT-23-6 Evaluation Board User’s Guide 1.3.1.2 PICKIT SERIAL ANALYZER PC SOFTWARE SET-UP FOR DAC DEVICE PROGRAMMING AND ANALOG VOLTAGE OUTPUT MEASUREMENT 1. Install the PICkit Serial Analyzer software in your computer. 2. Connect the USB cable between the PICkit Serial Analyzer and your PC. 3. Run the PICkit Serial PC Software: It will open up the following graphic user interface (GUI). Click Next > and follow the instructions: 4. Select the I2C Master option radio button for the Communication Mode type and click the Next > button. DS51669A-page 8 © 2007 Microchip Technology Inc. Quick Start Instructions 5. Select either 100 kHz option or 400 kHz option radio button and click the Next > button. Note: The MCP4725 SOT-23-6 Evaluation Board supports the I2C bus data rate up to 3.4 MHz, but the current version of the PICkit Serial Analyzer only supports the I2C bus data rate up to 400 kHz. 6. Select No on Device Pullups and click the Next > button. Note: The MCP4725 SOT-23-6 Evaluation Board has its own pull-up resistors © 2007 Microchip Technology Inc. DS51669A-page 9 MCP4725 SOT-23-6 Evaluation Board User’s Guide 7. Select the Voltage Source option for the MCP4725 SOT-23-6 Evaluation Board and click the Next > button. Case 1: When you use VDD from the PICkit Serial Analyzer: If you choose PICkit Serial will power my device option, and the 5 Volt option as shown below, the MCP4725 SOT-23-6 Evaluation Board is powered by the 5 VDC from the PICkit Serial Analyzer through the J1 connector. In this case, make sure that the JP2 jumper on the MCP4725 SOT-23-6 Evaluation Board is connected. You can also click on the Other option and move the slide bar for other than 5 volts. Case 2: When you use your own VDD: If you want to provide your own VDD voltage through the VDD terminal on the MCP4725 SOT-23-6 Evaluation Board, then do not select the PICkit Serial will power my device option. In this case, you have to remove the JP2 jumper on the board and provide the VDD at the VDD terminal. DS51669A-page 10 © 2007 Microchip Technology Inc. Quick Start Instructions 8. Click the OK button. You have done all PICkit Serial Analyzer Configuration Set-up. You are now ready to program the MCP4725 device using the PICkit Serial Analyzer. © 2007 Microchip Technology Inc.

The data in the EEPROM is non-volatile. To check this non-volatile data, you can remove the VDD from the MCP4725 SOT-23-6 Evaluation Board once, and bring back up the VDD again. You will see the same analog voltage output at the VOUT terminal. DS51669A-page 16 © 2007 Microchip Technology Inc. Quick Start Instructions 6. Reading the DAC Register Data using the PICkit Serial Analyzer This experiment can be done in two steps: (a) Write the DAC Register with Fast Mode Command.
