3 This device is a 12-bit A-D converter with 4 inputs.
5 The inputs can be used single ended or in certain differential combinations.
7 For configuration all possible combinations are mapped to 8 channels:
8 0: Voltage over AIN0 and AIN1.
9 1: Voltage over AIN0 and AIN3.
10 2: Voltage over AIN1 and AIN3.
11 3: Voltage over AIN2 and AIN3.
12 4: Voltage over AIN0 and GND.
13 5: Voltage over AIN1 and GND.
14 6: Voltage over AIN2 and GND.
15 7: Voltage over AIN3 and GND.
17 Each channel can be configured individually:
18 - pga is the programmable gain amplifier (values are full scale)
21 2: +/- 2.048 V (default)
25 - data_rate in samples per second
38 - compatible : must be "ti,ads1015"
39 - reg : I2C bus address of the device
40 - #address-cells : must be <1>
41 - #size-cells : must be <0>
43 The node contains child nodes for each channel that the platform uses.
48 compatible = "ti,ads1015";
53 [ child node definitions... ]
60 - reg : the channel number
64 - ti,gain : the programmable gain amplifier setting
65 - ti,datarate : the converter data rate
