| 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, |

| 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. |
