-Description
------------
-
-The Maxim MAX517/518/519 is an 8-bit DAC on the I2C bus. The following table
-shows the different feature sets of the variants MAX517, MAX518 and MAX519:
-
-Feature                              MAX517 MAX518 MAX519
---------------------------------------------------------------------------
-One output channel                   X
-Two output channels                         X      X
-Simultaneous output updates                 X      X
-Supply voltage as reference                 X
-Separate reference input             X
-Reference input for each DAC                       X
-
-Via the iio sysfs interface, there are three attributes available: out1_raw,
-out2_raw and out12_raw. With out1_raw and out2_raw, the current output values
-(0..255) of the DACs can be written to the device. out12_raw can be used to set
-both output channel values simultaneously.
-
-With MAX517, only out1_raw is available.
-
-Via out1_scale (and where appropriate, out2_scale), the current scaling factor
-in mV can be read.
-
-When the operating system goes to a power down state, the Power Down function
-of the chip is activated, reducing the supply current to 4uA.
-
-On power-up, the device is in 0V-output state.
