DESCRIPTION

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.

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.

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.

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.

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.

The device is available in a small 6-pin SOT-23

package.
