Analog to digital converter for converting multiple analog input signals to corresponding digital output signals during one conversion cycle

摘要

An analog-to-digital converter converts multiple analog signals to multiple digital signals during a single conversion period. The converter comprises a multiple input integrator stage which provides an output voltage that is selectively compared to a multiplicity of voltages. The comparison voltages include reference voltages and additional signal inputs. A plurality of UP counters measure the number of clock pulses generated by a clock generator and enable the calculation of the output function.
