Abstract
A controller receives an M-bit input and generates, in response, an S-bit upper range binary data feeding S-bit high range DAC and an R-bit lower range data feeding an R-bit low range DAC. The controller detects transition points in the M-bit input and in response, adds a transition data to the S-bit data equal to at least one least significant bit of the S-bit data and subtracts a value from the R-bit data equal to the transition data. The transition points and the transition data are detected and added at points avoiding such transitions at a full scale value of the R-bit data.
