Abstract: PROBLEM TO BE SOLVED: To minimize power consumption at A/D conversion by making the number of conversion bits at the A/D conversion variable so as to optimize the A/D conversion accuracy corresponding to the conversion accuracy requirements of a signal. SOLUTION: A D/A converter 3 coverts a reference voltage code signal 103 and gives the converted signal to a voltage comparator 1 at a reference voltage signal 104.

The comparison operations are repeated and the circuit 4 confirms each bit of the register 2 sequentially in the order of higher-significant bits.  Then a detector 5 compares the value of the signal 108 with that of the count 107 and when they are equal, the detector 5 provides the output of a conversion end signal 109 to the circuit 4. Then the circuit 4 interrupts the comparison and provides the output of the content of the register 2 as a conversion result 106.

Abstract: PURPOSE:To obtain a microcomputer incorporated in a D/A converter in which the output range of an analog signal can be set. CONSTITUTION:A CPU 7 sets the upper limit value and lower limit value of a digital signal equivalent to the maximum value and minimum value of an output analog signal at each register 5 and 6 before D/A conversion. Each time the CPU 7 transmits the digital signal to be D/A converted to a register 1, a control circuit 3 compares the digital signal to be D/A converted of the register 1 with the upper limit value and lower limit value of each digital signal of the registers 5 and 6.
