Description:
- Reading gives the state of AC excitation.
- Writing '1' enables AC excitation.
+ 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.

Description:
- This bridge switch is used to disconnect it when there is a
- need to minimize the system current consumption.
- Reading gives the state of the bridge switch.
- Writing '1' enables the bridge switch.
+ 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.
