+What: /sys/.../iio:deviceX/ac_excitation_en
+KernelVersion: 3.1.0
+Contact: linux-iio@vger.kernel.org
+Description:
+ This attribute, if available, is used to enable the AC
+ excitation mode found on some converters. In ac excitation mode,
+ the polarity of the excitation voltage is reversed on
+ alternate cycles, to eliminate DC errors.

+What: /sys/.../iio:deviceX/bridge_switch_en
+KernelVersion: 3.1.0
+Contact: linux-iio@vger.kernel.org
+Description:
+ This attribute, if available, is used to close or open the
+ bridge power down switch found on some converters.
+ In bridge applications, such as strain gauges and load cells,
+ the bridge itself consumes the majority of the current in the
+ system. To minimize the current consumption of the system,
+ the bridge can be disconnected (when it is not being used
+ using the bridge_switch_en attribute.
