description: Microchip MCP4728 12-bit 4-channel DAC

compatible: "microchip,mcp4728"

include: [dac-controller.yaml, i2c-device.yaml]

properties:
    "#io-channel-cells":
      const: 1

    voltage_reference:
      type: array
      required: true
      description: |
        DAC voltage reference select.
        0 - Vdd
        1 - Internal voltage reference (2.048V)
        Note: array entries correspond to the successive channels

    power_down_mode:
      type: array
      required: true
      description: |
        Power-down mode select.
        0 - normal mode
        1 - Vout is loaded with 1 kOhm resistor to ground
        2 - Vout is loaded 100 kOhm resistor to ground
        3 - Vout is loaded with 500 kOhm resistor to ground
        Note: with values bigger than 0 most of channel circuits are powered off
        Note: array entries correspond to the successive channels

    gain:
      type: array
      default: [0, 0, 0, 0]
      description: |
        Gain selection bit.
        0 = x1 (gain of 1)
        1 = x2 (gain of 2)
        Note: applicable only when internal Vref is selected
        Note: array entries correspond to the successive channels
