Description

The MCP4728 device is a quad, 12-bit voltage output

Digital-to-Analog Convertor (DAC) with nonvolatile

memory (EEPROM). Its on-board precision output

amplifier allows it to achieve rail-to-rail analog output

swing.

The DAC input codes, device configuration bits, and

memory (EEPROM) by using I

commands. The nonvolatile memory feature enables

the DAC device to hold the DAC input codes during

power-off time, allowing the DAC outputs to be

available immediately after power-up with the saved

settings. This feature is very useful when the DAC

device is used as a supporting device for other devices

in the application’s network.

The MCP4728 device has a high precision internal

voltage reference (V

the internal reference or external reference (V

each channel individually.

Each channel can be operated in Normal mode or

Power-Down

configuration register bits. In Power-Down mode, most

of the internal circuits in the powered down channel are

turned off for power savings, and the output amplifier

can be configured to present a known low, medium, or

high resistance output load.

The MCP4728 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 MCP4728 has a two-wire I

interface for standard (100 kHz), fast (400 kHz), or high

speed (3.4 MHz) mode.

The MCP4728 DAC is an ideal device for applications

requiring design simplicity with high precision, and for

applications requiring the DAC device settings to be

saved during power-off time.

The MCP4728 device is available in a 10-lead MSOP

package and operates from a single 2.7V to 5.5V

supply voltage.
