Filed: 1990-02-15
Abstract: PURPOSE:To enhance the utilization efficiency of a chip area and to obtain a hysteresis characteristic with respect to an analog signal by using a 4-phase clock pulse in spite of the employment of one set each of a comparison section and a D/A conversion section. CONSTITUTION:Digital values corresponding to analog voltages 1.1V, 3.9V respectively are set to level setting registers LXA, LXB. outputs DD1, DD2 are respectively the outputs of latches LX31, LX32, the output DD1 rises and falls at a low analog signal. Since the output DD2 is active at a higher level than the output DD1, the output of the latch LX31 rises faster and falls slower than the output of the latch LX32. Only when the output of a latch LX34 is at a low level, the output DD3 goes to a high level, and the output DD3 rises when the analog signal reaches a high setting value and falls when the analog signal reaches a low setting value, thereby realizing the hysteresis characteristic.
