4.3 Output ranges

Output value
The following table shows the representation of the binary analog values and the
corresponding decimal and hexadecimal representation of the units of the analog values.
The table below shows the resolutions 11, 12, 13, and 15 bit + sign. Each analog value is
entered left aligned in the ACCU. The bits marked with "x" are set to "0".
