7 title: IIO Common Properties for ADC Channels
10 - Jonathan Cameron <[email protected]>
13 A few properties are defined in a common way ADC channels.
17 pattern: "^channel(@[0-9a-f]+)?$"
29 description: If provided, the channel is to be used in bipolar mode.
31 diff-channels:
32 $ref: /schemas/types.yaml#/definitions/uint32-array
37 to both the positive and negative inputs of a differential ADC.
41 positive and negative inputs which can be used to measure differential
43 the 'reg' property for both inputs (i.e. diff-channels = <reg reg>).
45 single-channel:
48 When devices combine single-ended and differential channels, allow the
50 differential channels). If this and diff-channels are not present reg
51 shall be used instead.
53 common-mode-channel:
56 Some ADCs have differential input pins that can be used to measure
57 single-ended or pseudo-differential inputs. This property can be used
58 in addition to single-channel to signal software that this channel is
61 The input pair is specified by setting single-channel to the positive
62 input pin and common-mode-channel to the negative pin.
64 settling-time-us:
68 oversampling-ratio:
71 Oversampling is used as replacement of or addition to the low-pass filter.
