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]

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
