ABSTRACT:
A dual channel A/D and D/A converter includes a first channel converter, a second channel converter, and a reference generator all formed on a single semiconductor substrate. The reference generator is disposed intermediate the first channel converter and the second channel converter for effecting crosstalk isolation therebetween. The dual channel converter is formed of a unique differential structure having "coaxial" isolation of bus lines and interconnections, thereby achieving a higher degree of unwanted channel-to-channel crosstalk.
