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 (V_DD

• Rail-to-Rail Output

)

• Low Power Consumption

• Single-Supply Operation: 2.7V to 5.5V

• I²C^TMInterface:

- 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.
