| The MAX127 is a multirange, 12-bit data acquisition system (DAS) providing |
| 8 analog input channels that are independently software programmable for |
| a variety of ranges. The available ranges are {0,5V}, {0,10V}, {-5,5V} |
| The MAX127 features a 2-wire, I2C-compatible serial interface that allows |
| communication among multiple devices using SDA and SCL lines. |
| ============== ============================================================== |
| in[0-7]_input The input voltage (in mV) of the corresponding channel. |
| in[0-7]_min The lower input limit (in mV) for the corresponding channel. |
| ADC range and LSB will be updated when the limit is changed. |
| For the MAX127, it will be adjusted to -10000, -5000, or 0. |
| in[0-7]_max The higher input limit (in mV) for the corresponding channel. |
| ADC range and LSB will be updated when the limit is changed. |
| For the MAX127, it will be adjusted to 0, 5000, or 10000. |
