mcp48x1dac driver supports the MCP48x1 family of
  digital to analog converters. The digital values to be converted to analog
  signal are passed through the
  sysctl(8) node.
The driver reports the current voltage output on the chip's DAC
    channel through the envsys(4)
    API. It calculates these values assuming that internal 2.048V reference
    voltage (Vref) is used.
The following table shows the supported chips. The type of the chip can be selected with the flags argument in the config file.
| Designation | Resolution | flags | 
| MCP4801 | 8 bits | 0 | 
| MCP4811 | 10 bits | 1 | 
| MCP4821 | 12 bits | 2 |
