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
I2C address bits are programmable to the nonvolatile
memory (EEPROM) by using I2C serial interface
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 (VREF = 2.048V). The user can select
the internal reference or external reference (VDD) for
each channel individually.
Each channel can be operated in Normal mode or
Power-Down
mode
individually
by
setting
the
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 I2C compatible serial
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.
