When REJ60 is set, a filter notch is placed at 56 60 Hz when the sinc filter first notch is at 50 Hz. This allows 57 simultaneous 50 Hz/ 60 Hz rejection. 58 type: boolean 59 60 adi,refin2-pins-enable: 61 description: | 62 External reference applied between the P1/REFIN2(+) and P0/REFIN2(−) pins. 63 type: boolean 64 65 adi,buffer-enable: 66 description: | 67 Enables the buffer on the analog inputs. If cleared, the analog inputs 68 are unbuffered, lowering the power consumption of the device. If this 69 bit is set, the analog inputs are buffered, allowing the user to place 70 source impedances on the front end without contributing gain errors to 71 the system. 72 type: boolean 73 74 adi,burnout-currents-enable: 75 description: | 76 When this bit is set to 1, the 500 nA current sources in the signal 77 path are enabled. When BURN = 0, the burnout currents are disabled. 78 The burnout currents can be enabled only when the buffer is active 79 and when chop is disabled. 80 type: boolean 81 82 bipolar: 83 description: see Documentation/devicetree/bindings/iio/adc/adc.yaml 84 type: boolean 85 86required: 87 - compatible 88 - reg 89 - clocks 90 - clock-names 91 - interrupts 92 - dvdd-supply 93 - avdd-supply 94 - spi-cpol 95 - spi-cpha 96 97additionalProperties: false 98 99examples: 100 - | 101 spi0 { 102 #address-cells = <1>; 103 #size-cells = <0>; 104 105 adc@0 { 106 compatible = "adi,ad7192"; 107 reg = <0>; 108 spi-max-frequency = <1000000>; 109 spi-cpol; 110 spi-cpha; 111 clocks = <&ad7192_mclk>; 112 clock-names = "mclk"; 113 interrupts = <25 0x2>; 114 interrupt-parent = <&gpio>; 115 dvdd-supply = <&dvdd>; 116 avdd-supply = <&avdd>; 117 118 adi,refin2-pins-enable; 119 adi,rejection-60-Hz-enable; 120 adi,buffer-enable; 121 adi,burnout-currents-enable; 122 }; 123 };
