+ adi,rejection-60-Hz-enable:
+ description: |
+ This bit enables a notch at 60 Hz when the first notch of the sinc
+ filter is at 50 Hz. When REJ60 is set, a filter notch is placed at
+ 60 Hz when the sinc filter first notch is at 50 Hz. This allows
+ simultaneous 50 Hz/ 60 Hz rejection.

+ External reference applied between the P1/REFIN2(+) and P0/REFIN2(−) pins.
+ type: boolean
+
+ adi,buffer-enable:
+ description: |
+ Enables the buffer on the analog inputs. If cleared, the analog inputs
+ are unbuffered, lowering the power consumption of the device. If this
+ bit is set, the analog inputs are buffered, allowing the user to place
+ source impedances on the front end without contributing gain errors to
+ the system.
+ type: boolean
+
+ adi,burnout-currents-enable:
+ description: |
+ When this bit is set to 1, the 500 nA current sources in the signal
+ path are enabled. When BURN = 0, the burnout currents are disabled.
+ The burnout currents can be enabled only when the buffer is active
+ and when chop is disabled.
