and R
resistance should be significantly greater (> 100 times)
the resistance value of the MCP4011. This allows each
increment or decrement in the MCP4011 to be a fine
adjustment of the offset voltage. The input voltage of

voltage. The gain is adjusted by the MCP4012. If the
resistance value of the MCP4012 is small compared to
the resistance value of R
of the gain. If the resistance value of the MCP4012 is
equal (or large) compared to the resistance value of R
then this is a course adjustment of the gain. In general,
trim the course adjustments first and then trim the fine
adjustments.
