| What: /sys/bus/iio/devices/iio:deviceX/ac_excitation_en | |
| KernelVersion: | |
| 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. | |

| KernelVersion: | |
| 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. | |

| Description: | |
| Measure voltage from AIN2 pin connected to AIN(+) | |
| and AIN(-) shorted. |
