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.
