The AD7606C-16 and AD7606C-18 are pretty similar with the AD7606B. The main difference between AD7606C-16 & AD7606C-18 is the precision in bits (16 vs 18). Because of that, some scales need to be defined for the 18-bit variants, as they need to be computed against 2**18 (vs 2**16 for the 16 bit-variants). Because the AD7606C-16,18 also supports bipolar & differential channels, for SW-mode, the default range of 10 V or ±10V should be set at probe. On reset, the default range (in the registers) is set to value 0x3 which corresponds to '±10 V single-ended range', regardless of bipolar or differential configuration. Aside from the scale/ranges, the AD7606C-16 is similar to the AD7606B. The AD7606C-18 variant offers 18-bit precision. Because of this, the requirement to use this chip is that the SPI controller supports padding of 18-bit sequences to 32-bit arrays.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
