User manual for the Microchip MCP4725 12‑bit DAC in a SOT‑23‑6 package, covering features, programming with PICkit and wiring details.
This manual introduces the MCP4725 SOT‑23‑6 digital‑to‑analog converter, its key features, and how to program it using a PICkit programmer. It includes a brief overview of the device, a description of the DAC and EEPROM functions, and a list of required components.
The document provides wiring diagrams, I²C interface details, recommended pull‑up resistor values, and a bill of materials (BOM). It also contains troubleshooting tips and contact information for Microchip technical support. This manual is written in Chinese.
| Package | SOT‑23‑6 |
|---|---|
| I²C clock speed (max) | 400 kHz |
| Supported I²C clock speeds | 100 kHz, 400 kHz, 3.4 MHz |
Connect the PICkit programmer to the MCP4725 as shown in the wiring diagram and use the PICkit software to write the desired DAC values to the device.
The MCP4725 uses the SCL and SDA pins for I²C communication, along with VDD and VSS for power.
The device can operate at 100 kHz, 400 kHz, and up to 3.4 MHz I²C clock frequencies.
