| * se_input: bool (default Y) |
| Single ended operation - set to N for differential mode |
| * int_vref: bool (default Y) |
| Operate with the internal 2.5V reference - set to N for external reference |
| * vref_mv: int (default 2500) |
| If using an external reference, set this to the reference voltage in mV |
| This driver implements support for the Texas Instruments ADS7828. |
| This device is a 12-bit 8-channel A-D converter. |
| It can operate in single ended mode (8 +ve inputs) or in differential mode, |
| where 4 differential pairs can be measured. |
| The chip also has the facility to use an external voltage reference. This |
| may be required if your hardware supplies the ADS7828 from a 5V supply, see |
| the datasheet for more details. |
