- Module Parameters
- -----------------
- * 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
- Description
- -----------
- 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.
