MCP4725  
12-Bit Digital-to-Analog Converter with EEPROM Memory  
in SOT-23-6  
Features  
DESCRIPTION  
• 12-Bit Resolution  
The MCP4725 is a low-power, high accuracy, single  
channel, 12-bit buffered voltage output Digital-to-Ana-  
log Convertor (DAC) with non-volatile memory  
(EEPROM). Its on-board precision output amplifier  
allows it to achieve rail-to-rail analog output swing.  
• On-Board Non-Volatile Memory (EEPROM)  
• ±0.2 LSB DNL (typical)  
• External A0 Address Pin  
• Normal or Power-Down Mode  
• Fast Settling Time of 6 µs (typical)  
The DAC input and configuration data can be  
programmed to the non-volatile memory (EEPROM) by  
the user using I2C interface command. The non-volatile  
memory feature enables the DAC device to hold the  
DAC input code during power-off time, and the DAC  
output is available immediately after power-up. This  
feature is very useful when the DAC device is used as  
a supporting device for other devices in the network.  
• External Voltage Reference (VDD  
• Rail-to-Rail Output  
)
• Low Power Consumption  
• Single-Supply Operation: 2.7V to 5.5V  
• I2CTM Interface:  
- Eight Available Addresses  
- Standard (100 kbps), Fast (400 kbps), and  
High-Speed (3.4 Mbps) Modes  
The device includes a Power-On-Reset (POR) circuit to  
ensure reliable power-up and an on-board charge  
pump for the EEPROM programming voltage. The  
DAC reference is driven from VDD directly. In  
power-down mode, the output amplifier can be config-  
ured to present a low, medium, or high resistance out-  
put load.  
• Small 6-lead SOT-23 Package  
• Extended Temperature Range: -40°C to +125°C  
Applications  
• Set Point or Offset Trimming  
The MCP4725 has an external A0 address pin. This A0  
pin can be tied to VDD or VSS of the user’s application  
board.  
The MCP4725 has a two-wire I2C™ compatible serial  
interface for standard (100 kHz), fast (400 kHz), or high  
speed (3.4 MHz) mode.  
• Sensor Calibration  
• Closed-Loop Servo Control  
• Low Power Portable Instrumentation  
• PC Peripherals  
• Data Acquisition Systems  
Block Diagram  
The MCP4725 is an ideal DAC device where design  
simplicity and small footprint is desired, and for applica-  
tions requiring the DAC device settings to be saved  
during power-off time.
