-Microchip mcp4725 and mcp4726 DAC device driver
-
-Required properties:
- - compatible: Must be "microchip,mcp4725" or "microchip,mcp4726"
- - reg: Should contain the DAC I2C address
- - vdd-supply: Phandle to the Vdd power supply. This supply is used as a
- voltage reference on mcp4725. It is used as a voltage reference on
- mcp4726 if there is no vref-supply specified.
-
-Optional properties (valid only for mcp4726):
- - vref-supply: Optional phandle to the Vref power supply. Vref pin is
- used as a voltage reference when this supply is specified.
- - microchip,vref-buffered: Boolean to enable buffering of the external
- Vref pin. This boolean is not valid without the vref-supply. Quoting
- the datasheet: This is offered in cases where the reference voltage
- does not have the current capability not to drop its voltage when
- connected to the internal resistor ladder circuit.
-
-Examples:
-
- /* simple mcp4725 */
- mcp4725@60 {
- compatible = "microchip,mcp4725";
- reg = <0x60>;
- vdd-supply = <&vdac_vdd>;
- };
-
- /* mcp4726 with the buffered external reference voltage */
- mcp4726@60 {
- compatible = "microchip,mcp4726";
- reg = <0x60>;
- vdd-supply = <&vdac_vdd>;
- vref-supply = <&vdac_vref>;
- microchip,vref-buffered;
- };
