Title: Analogue / digital converter
Inventor: RICHIYAADO EE BAUMUGAATONAA
IPC: H03F3/00
Filed: 1993-04-30
Abstract: PURPOSE: To obtain an A/D converter which can be stably apply an offset even under a high-noise condition by differentially inputting signals and offsets and converting the signals into digital values and, when the digital values continuously exceed a threshold while a prescribed number of signal are converted, generating an offset. CONSTITUTION: An offset offsetting D/A converter 740 can be controlled by either an externally supplied value 754 or an internal logical control 736. When the control 736 is selected, the digital output 724 of a counter 722 is monitored by offset logic 736. When an A/D counter sample having a programmable number as the value of the output 724 exceeds a programmable threshold, the two- way offset value 738 in the logic control 736 is incremented. Then, the D/A converter 740 generates a differential offset voltage to be subtracted from input signals 416 and 418. A serial digital output value from this chip contains 1-bit offset information and the direction of the output value can be inferred from the preceding A/D output value. Therefore, an external processor can track the offset value by updating a register.
