DESCRIPTION
The MCP4725 is a low-power, high accuracy, single
channel, 12-bit buffered voltage output Digital-to-
Analog 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 I
2
C 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 V
DD
directly. In power-
down mode, the output amplifier can be configured to
present a known low, medium, or high resistance
output load.
The MCP4725 has an external A0 address bit selection
pin. This A0 pin can be tied to V
DD
or V
SS
of the user’s
application board.
The MCP4725 has a two-wire I
2
C™ 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
applications requiring the DAC device settings to be
saved during power-off time.
The device is available in a small 6-pin SOT-23
package.
