      4Description:
      5		This attribute, if available, is used to enable the AC
      6		excitation mode found on some converters. In ac excitation mode,
      7		the polarity of the excitation voltage is reversed on
      8		alternate cycles, to eliminate DC errors.

     13Description:
     14		This attribute, if available, is used to close or open the
     15		bridge power down switch found on some converters.
     16		In bridge applications, such as strain gauges and load cells,
     17		the bridge itself consumes the majority of the current in the
     18		system. To minimize the current consumption of the system,
     19		the bridge can be disconnected (when it is not being used
     20		using the bridge_switch_en attribute.

     23KernelVersion:
     24Contact:	linux-iio@vger.kernel.org
     25Description:
     26		Initiates the system calibration procedure. This is done on a
     27		single channel at a time. Write '1' to start the calibration.

     30KernelVersion:
     31Contact:	linux-iio@vger.kernel.org
     32Description:
     33		Measure voltage from AIN2 pin connected to AIN(+)
     34		and AIN(-) shorted.

     37KernelVersion:
     38Contact:	linux-iio@vger.kernel.org
     39Description:
     40		Reading returns a list with the possible calibration modes.
     41		There are two available options:
     42		"zero_scale" - calibrate to zero scale
     43		"full_scale" - calibrate to full scale

     45What:		/sys/bus/iio/devices/iio:deviceX/in_voltagex_sys_calibration_mode
     46KernelVersion:
     47Contact:	linux-iio@vger.kernel.org
     48Description:
     49		Sets up the calibration mode used in the system calibration
     50		procedure. Reading returns the current calibration mode.
     51		Writing sets the system calibration mode.
