MCP4728 - Quad Digital-to-Analog Converter

General 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.

Key Features

  • 12-Bit Voltage Output DAC with Four Buffered Outputs.
  • On-Board Nonvolatile Memory (EEPROM) for DAC Codes and I2C™ Address Bits.
  • Internal or External Voltage Reference Selection.
  • Output Voltage Range: - Using Internal VREF (2.048V): 0.000V to 2.048V with Gain Setting = 1 0.000V to 4.096V with Gain Setting = 2 - Using External VREF (VDD): 0.000V to VDD.
  • ±0.2 Least Significant Bit (LSB) Differential Nonlinearity (DNL) (typical).
  • Fast Settling T.
