53 adi,rejection-60-Hz-enable:
55 This bit enables a notch at 60 Hz when the first notch of the sinc
56 filter is at 50 Hz. When REJ60 is set, a filter notch is placed at
57 60 Hz when the sinc filter first notch is at 50 Hz. This allows
58 simultaneous 50 Hz/ 60 Hz rejection.
61 adi,refin2-pins-enable:
63 External reference applied between the P1/REFIN2(+) and P0/REFIN2(−) pins.
68 Enables the buffer on the analog inputs. If cleared, the analog inputs
69 are unbuffered, lowering the power consumption of the device. If this
70 bit is set, the analog inputs are buffered, allowing the user to place
71 source impedances on the front end without contributing gain errors to
75 adi,burnout-currents-enable:
77 When this bit is set to 1, the 500 nA current sources in the signal
78 path are enabled. When BURN = 0, the burnout currents are disabled.
79 The burnout currents can be enabled only when the buffer is active
80 and when chop is disabled.
