In precisely taking shape and processing product,generally D/A output is regarded as the output control signal of the control system,the minimum increment of D/A output determines the control precision of the control system,Subdividing minimum increment of D/A output can increase resolution and increase the control precision of the control system greatly.The new way to Subdividing minimum increment of D/A output is given.Using three D/A converters,through subdividing the increase of two D/A continue input data,the Resolution of D/A output is increased.The choosing and using of the precision amplifier TLC2652 are introduced in the paper.When the precision amplifier is right,subdividing minimum increment of D/A output can change 10 bits and 8 bits resolution of D/A into 18 bits and 16 bits to 32 bits.
