The MC145402 is a 13–bit linear monotonic digital–to–analog and analog–  
to–digital converter implemented in a single silicon–gate CMOS IC. Potential  
applications include analog interface for Digital Signal Processor (DSP)  
applications, high speed modems, telephone systems, SONAR, Adaptive  
Differential Pulse Code Modulation (ADPCM) converters, echo cancellers,  
repeaters, voice synthesizers, and music synthesizers.
