DESCRIPTION

· The MCP4728 is a quad, 12-bit voltage output DAC with nonvolatile memory (EEPROM).
· It features on-board precision output amplifiers for rail-to-rail analog output swing.
· DAC input codes, configuration bits, and I2C address bits are programmable via I2C interface.
· Nonvolatile memory retains settings during power-off, enabling immediate operation post power-up.
· Includes a Power-on Reset (POR) circuit and an on-board charge pump for EEPROM programming.
· Operates from a single 2.7V to 5.5V supply and is available in a 10-lead MSOP package.

FEATURES

· 12-Bit resolution with four buffered outputs.
· On-board EEPROM for DAC codes and I2C address bits.
· Selectable internal (2.048V) or external (VDD) voltage reference.
· Output voltage range: 0.000V to 2.048V or 0.000V to VDD.
· ±0.2 LSB DNL and fast settling time of 6 µs.
· Normal or Power-Down mode for low power consumption.
· I2C interface with programmable address bits, supporting up to 3.4 Mbps.
· Extended temperature range: -40°C to +125°C.

APPLICATIONS

· Set point or offset adjustment.
· Sensor calibration and closed-loop servo control.
· Low power portable instrumentation and PC peripherals.
· Programmable voltage and current sources.
· Industrial process control and instrumentation.
· Bias voltage adjustment for power amplifiers.
