MCP4728

12-Bit, Quad Digital-to-Analog Converter with EEPROM Memory

Features

Description

• 12-Bit Voltage Output DAC with 4 Buffered

Outputs

The MCP4728 device is a quad, 12-bit 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.

• On-Board Non-Volatile Memory (EEPROM) for

DAC Codes and I²C^TMAddress Bits

• Internal or External Voltage Reference Selection

• Output Voltage Range:

The DAC input codes, device configuration bits, and

I²C address bits are programmable to the non-volatile

memory (EEPROM) by using I²C serial interface

commands. The non-volatile 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 applications network.

- Using Internal V_REF(2.048V):

0.000V to 2.048V with Gain Setting = 1

0.000V to 4.096V with Gain Setting = 2

- Using External V_REF(V_DD): 0.000V to V_DD

• ±0.2 LSB DNL (typical)

• Fast Settling Time: 6 µs (typical)

• Normal or Power-Down Mode

• Low Power Consumption

The MCP4728 device has a high precision internal

voltage reference (V_REF= 2.048V). The user can select

the internal reference or external reference (V_DD) for

each channel individually.

• Single-Supply Operation: 2.7V to 5.5V

• I²C Interface:

- Address bits: User Programmable to

EEPROM

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.

- Standard (100 kbps), Fast (400 kbps) and

High Speed (3.4 Mbps) Modes

• 10-Lead MSOP Package

• Extended Temperature Range: -40°C to +125°C

Applications

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.

• Set Point or Offset Adjustment

• Sensor Calibration

• Closed-Loop Servo Control

• Low Power Portable Instrumentation

• PC Peripherals

• Programmable Voltage and Current Source

• Industrial Process Control

• Instrumentation

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.
