24Description
25-----------
26
27This driver implements support for the Texas Instruments ADS7828.
28
29This device is a 12-bit 8-channel A-D converter.
30
31It can operate in single ended mode (8 +ve inputs) or in differential mode,
32where 4 differential pairs can be measured.
33
34The chip also has the facility to use an external voltage reference.  This
35may be required if your hardware supplies the ADS7828 from a 5V supply, see
36the datasheet for more details.
